Enzyme kinetics General procedure: The reaction buffer used for determination of the specific activity consisted of 20 mM BisTris (pH 7.0), 50 mM KCl and 20 mM CaCl2. CoCl2 was added to a concentration of 5 mM shortly before starting the reaction. The 5NT protein samples were diluted in reaction buffer supplemented with 50 μg/ml BSA to prevent adhesion to the reaction tubes and with 5 mM CoCl2. The reactions were started at room temperature by addition of 180 μl of reaction buffer containing the respective concentration of substrate to 20 μl of protein sample. Released phosphate was detected according to a modified malachite green assay [10,11]. The reaction was restricted to 10% phosphate release. After 20 min of color development the samples were measured at a Tecan-Sunrise Microplate Reader (Crailsheim/Germany) at a wavelength of 620 nm. Experimental data were fitted according to Michaelis-Menten using OriginPro 8G. It should be pointed out that the substrate concentrations used here were partly not sufficient to reach the saturation plateau. Due to an increased autohydrolysis of the substrates it was not possible to use higher substrate concentrations in the malachite green assay. With the assumption that the AMP concentration was much smaller than the Km-value the specificity constant of 5NT-NDom with AMP was calculated from the slope of the curve shown in Fig. 4B.

With Acinetobacter baumannii recombinant acid phosphatase; nickel dichloride; bovine serum albumin In water Cooling with ice; Enzymatic reaction; Acid phosphatase assay General procedure: Unless indicated otherwise, reaction mixtures contained 2.0 mM PNPP (Sigma Chemical Co.)or phosphorylated compounds (Sigma Chemical Co.), 0.20MMES (Sigma Chemical Co.)buffer, pH 6.0, 2.0 mM NiCl2, and 0.080-0.30 μg total Acinetobacter baumannii rAcpA protein,and were brought to a final concentration of 0.186 μg/μL protein with addition of bovineserum albumin (BSA, BioRad Laboratories) in a total reaction volume of 200 μL (determinationof released phosphate) or 300 μL (determination of released paranitrophenol). All incubationswere carried out for 30 minutes at 37 °C after which time reactions were placed in an iceslurry for 3 minutes followed by addition of enzyme to the respective blanks and reactionswere terminated by heating at 65 °C for 10 minutes followed by immersion in an ice slurry for3 minutes. Released phosphate was determined by addition of 1.0 mL BIOMOL GREEN phosphatereagent (Enzo Life Sciences), and monitored at 620 nm using a Genesys 10 UV ScanningSpectrophotometer (Thermo Scientific). Paranitrophenol was monitored at 405 nm followingaddition of 1.7 mL 0.5MGlycine buffer, pH 10. Following subtraction of blank values, paranitrophenoland released phosphate were quantitated using paranitrophenol and phosphatestandard curves, respectively. All reactions, i.e., generation of paranitrophenol and release offree phosphate were linear with both time (30 minutes) and assay protein (0.30 μg, ~ 13.2 nM).Specific activity is expressed as nmoles paranitrophenol or free phosphate liberated mg-1s-1.

With pyruvate kinase; myokinase; Escherichia coli acetyl-CoA synthetase; coenzyme A; NADH; magnesium chloride; Cleland's reagent; lactate dehydrogenase; In aq. phosphate buffer; at 37℃;pH 7.5;Enzymatic reaction;Kinetics; The acetyl-CoA synthetase assay was based on the coupled assayreported by Williamson and Corkey [33]. AMP production was detectedvia a coupled enzyme assay in which myokinase (MK), pyruvate kinase(PK) and lactate dehydrogenase (LDH) couple AMP production toNADH oxidation. Standard acetyl-CoA synthetase assays (0.2 mL) wereperformed at 37 C in 50mM potassium phosphate buffer at pH 7.5containing 3.0mM PEP (phosphoenolpyruvate), 5 units MK, 1 unit PK,1.5 units LDH, 5mM MgCl2, 2.5mM <strong>[56-65-5]ATP</strong>, 1.5mM CoA, 0.1mM NADH,5mM acetate and 1mM DTT. The reaction was started by the additionof Acs. All reactions were performed in triplicate. Specific activity wascalculated using the extinction coefficient of NADH (6.22mM-1 cm-1)and was based on the oxidation of two molecules of NADH for eachAMP molecule released. One unit of Acs activity is defined as 1 mumole ofacetyl-CoA formed per minute at pH 7.5 and 37 C. Obtained milliunitsof absorbance per minute at 340 nm (Synergy H1 Hybrid Multi-ModeReader, Biotek), were converted to units of absorbance per minute bymeans of the PathCheck Sensor feature. Substrate concentrations werevaried from 0 to 0.5mM for <strong>[56-65-5]ATP</strong> and 0 to 2mM for acetate. Pseudofirst-order kinetic parameters were determined using Prism v6(GraphPad) analytical software and standard deviations were determinedfrom the three replicates. Statistical multiple comparison onewayANOVA has been carried out for kinetic parameters to know if thedifferences between parameters were or not significatively different.Acs inhibition assays were carried out employing a pyrophosphate detectionkit (Sigma Aldrich) following the commercial protocol.

The solution was evaporated to dryness. The residue was dissolved in methanol and re-evaporated twice. Subsequently, this procedure was repeated twice with anhydrous DMF (50 mL) using an oil pump. The residue was dissolved in 30 mL of anhydrous DMF and then imidazole (4.1 g, 60 mmol), 2,2'-dithiopyridine (10.6 g, 48 mmol) and triphenylphosphine (12.6 g, 48 mmol) were added. The solution was stirred for 2 hours at room temperature. It was then treated with 10 mL of 1 M sodium perchlorate solution in acetone (30 mL). The sodium salt of adenosine-5'-phosphoroimidazolate was obtained as a white precipitate, which was collected by centrifugation, washed with acetone (5*30 mL), and then dried in a desiccator. The product (2.25 g, 5.3 mmol, 88%) was used in the next step without further purification.

Preparation of the activated nucleotides General procedure: A mixture of a mononucleotide (AMP or UMP, 1.76mmol) and imidazole (22mmol) was added to DMF (10mL) in a 50-mL flask and the solvent was evaporated to dryness at reduced pressure. The evaporation was repeated twice with DMF (2×10mL) to remove residual water. The residue was dissolved in a mixture of DMF (10mL) with DMSO (10mL) and stirred with 2,2′-dithiodipyridine (6.5mmol), triphenylphosphine (6.36mmol), and TEA (6.5mmol) for 2h. The resulting product was recovered from the clear yellow reaction mixture as a precipitate by adding the reaction mixture drop wise to a solution of anhydrous NaClO4 (3.5g) in a mixture of ether (100mL), acetone (100mL) and TEA (20mL) with stirring. The stirring was continued for 30min (to ensure complete formation of the Na+ salt) and a colorless, flocculent solid was precipitated which was allowed to settle (30min). The supernatant is decanted and the remaining reaction mixture was centrifuged. The resulting colorless pellet was washed twice with a mixture of ether (100mL) and acetone (100mL) and then with ether (100mL) and dried overnight in a vacuum desiccator. The purity of ImpA and ImpU as determined by reverse phase HPLC was >99.5%.

With nucleoside triphosphate diphosphohydrolase from Legionella pneumophila; In aq. buffer; at 37 - 99℃; for 0.25h;Enzymatic reaction;Kinetics; The reaction mixture for the Lp1NTPDase inhibition assay contained 50 lL ADP (final concentration 500 lM) dissolved in assay buffer, 10 lL of test compound, and 30 lL of enzyme buffer in a reaction tube. The enzymatic reaction was initiated by adding 10 lL of enzyme solution to each test tube, carried out at 37Cfor 10 min and stopped by heating at 99C for 5 min. Then 100 lL of internal standard UMP (40 lM or 50lM) was added, 100 lL of the resulting solution was transferred to a CE vial and subjected to the CE.
With SmNPP5;Enzymatic reaction; SmNPP5 has additional promiscuity and has been shown to cleave substrates in addition to ADP. As a non-limiting example, SmNPP5 has been shown to cleave Ap3A (diadenosine triphosphate) into AMP and Pi (see e.g., FIG. 9A-FIG. 9C). As another non limiting example, SmNPP5 has been shown to cleave Ap4A (diadenosine tetraphosphate) into AMP and PPi (see e.g., FIG. 10A-FIG. 10C). Ap3A and Ap4A are both canonical ATPase inhibitors. Without wishing to be bound by theory, it is proposed that cleavage of Ap3 A or Ap4A by SmNPP5 can have an effect on coagulation, such as an anti-coagulation effect.

With bovine serum albumin; In aq. buffer; at 30℃;Enzymatic reaction; General procedure: Time course experiments were performed in PDE buffer + 0.05% (m/v) BSA at a <strong>[60-92-4]cAMP</strong>- or cCMP-concentration of 3 muM. The purified GST-tagged and truncated PDE7A1/2 was added at a concentration of 0.95 mug/ml, corresponding to 210 pmol/(min ml). Crude PDE7A1-containing Sf9 cell lysate was added to yield a final activity of 5 U/ml. The samples were incubated at 30 C under constant shaking. Aliquots were drawn at appropriate times, processed as described for the enzyme screening experiments (Section 2.2) and analyzed by HPLC-MS/MS as described in the Supplementary Methods. In all experiments, the samples were repeatedly subjected to short centrifugations (at least every 30 min) to avoid concentration changes by evaporation- and condensation processes.
With ethylenediaminetetraacetic acid; recombinant N-terminally GST-tagged human cardiac phosphodiesterase PDE3A (484?1141); magnesium chloride; BSA; In aq. buffer; at 30℃; for 0.0333333h;pH 7.5;Enzymatic reaction;Kinetics; Catalytic behavior; General procedure: For the determination of KM and Vmax values of PDE3A mediated <strong>[60-92-4]cAMP</strong> and cUMP hydrolysis, substrate concentrations between 0.1 and 6 muM (<strong>[60-92-4]cAMP</strong>) and between 1muM and 1.5 mM (cUMP) were used in 1× PDE buffer supplemented with 0.05% of BSA. The reaction was started by adding PDE3A to yield a final concentration of 0.1mug/ml and a final sample volume of 50 mul. Negative controls without PDE were run in parallel for each substrate concentration. All samples were run in duplicates and incubated for 15 min (cUMP) or 2 min (<strong>[60-92-4]cAMP</strong>) at 30 C under constant shaking (300 rpm). After that, 40 mul aliquots were drawn, heat-inactivated, and frozen overnight as described in the section about the time course experiments. In the next step, the samples were thawed and centrifuged(15 min, 20,800×g, 4 C) to remove precipitated protein. In case of samples with less than 10 muM of cNMPs, 10mul of the supernatant was diluted 1:4 with purified water. For cNMP concentrations of more than 10muM and less than 0.5 mM, the supernatant was diluted 1:200 (1:50, followed by 1:4) with purified water. Substrate concentrations higher than 0.5 mM were diluted 1:400 (1:100, followed by 1:4). Forty microliters of these dilutions were mixed 1:1 with tenofovir solution(100 ng/ml) to yield a final tenofovir concentration of 50 ng/ml and a final volume of 80 mul. The HPLC-MS/MS measurement was performed as previously described (Monzel et al.2014).
With rhodopsin fused to a C-terminal cyclic nucleotide phosphodiesterase domain; sodium chloride; sodium hydroxide; magnesium chloride; N-2-hydroxyethylpiperazine-N'-2-ethanesulfonic acid; In aq. buffer; at 20℃;pH 6.5;Irradiation; Enzymatic reaction; General procedure: HEK293T cells were transfected with plasmid pCDNA3.1-Rh-PDE by the calcium phosphate method. DMEM/F-12medium contained 0.5 M all-trans-retinal and penicillin andstreptomycin. The cells were harvested after 24 h and washed inbufferA(140mMNaCl, 3mMMgCl2, 50mMHEPES-NaOH,pH6.5). The cells were resuspended with buffer A and homogenizedusing a Potter-Elehjem grinder (Wheaton) and a syringewith a 27-gauge needle. The syringe was filled and drained fivetimes while stirring the homogenate. The protein amount wasdetermined by a BCA protein assay (Thermo Fisher Scientific).Samples were kept in the dark before measurement for at least2 h. Catalytic activity was measured at room temperature in 100l of buffer A with 1.6-1.8 g (in the case of cGMP) or 16-18g (in the case of <strong>[60-92-4]cAMP</strong>) of total protein in a 1.5-ml sampletube. The sample was illuminated with a xenon lamp (MAX-303, Asahi Spectra Co.) through a Y52 filter (7 mW mm2).Reaction was initiated by adding cyclic nucleotides (final concentration100 M). Aliquots were taken out at different timepoints, and the reactions were immediately terminated by adding100 l of 0.1 N HCl and frozen in liquid nitrogen. Afterthawing, the samples were centrifuged to remove the membranesand denatured proteins. Nucleotides (20 l of aliquot)were separated by HPLC (Shimadzu Corp., Kyoto, Japan) with aC18 reversed-phase column (Waters) and 100 mM potassiumphosphate (pH 5.9), 4 mM tetrabutylammonium iodide, and10% (v/v) methanol as eluent (12, 26). Nucleotides were monitoredat 254 nm. Data were evaluated with LabSolutions (Shimadzu).Peak areas were integrated and assigned to the eductcyclic nucleotide based on retention times of correspondingstandard compound.

42% With lithium chloride In water at 85℃; for 8h; Inert atmosphere; 7 EXAMPLE 7: Increasing polymer yield synthesis- based on manuscript As previously, two monomers were chosen adenosine 5’-monophosphate (AMP) and uridine 5’-monophosphate (UMP) in their acid forms rather than as sodium salts (Sigma-Aldrich). When dissolved in water at 10 mM concentration the pH of the solution is 2.5. Commercial polyadenylic acid (polyA) and polyuridylic acid (polyU) were used as polynucleotide control standards (Sigma-Aldrich). These were mixed in 1:1 mole ratios with respect to the bases to produce double stranded RNA (polyA-polyU). The effects on oligomerization of a variety of monovalent salts, including LiC1, NaC1, KC1, and NH4C1 weretested. During evaporation, the salts formed crystalline films when their solubility was exceeded. The growing crystals excluded other solutes such as the mononucleotides, producing highly concentrated eutectic phases within the salt matrix. A laboratory simulation of HD cyclesSimulations were carried out using glass slides with two wells on each slide that hold0.1 mL of the reaction mixture. Four slides were arranged on a laboratory hot plate set at thedesired temperature range, and a plastic flow box with 8 small holes (1 mm diameter) was set on the slides. Each hole was placed directly over a well so that carbon dioxide gas flowed onto the mixture at approximately 1 cc/sec into each well. The gas was used to exclude oxygen, but also to carry away water vapor from condensation reaction as ester bondsformed, thereby preventing hydrolytic back reactions. Reaction mixturesMononucleotides, AMP (10 mM) and UMP (10 mM), were initially mixed in a 1:1 volume ratio. The mononucleotides solution and 0.1 M monovalent salts were mixed in a 2:1 volume ratio so that the initial concentrations were 3.3 mM AMP and UMP, together with0.033 M salt. Because water evaporated during dehydration, these dilute solutions become highly concentrated and finally dry, so it is the ratios that are significant rather than the initial concentrations. In a typical experiment, the reactants were exposed to 1-16 cycles of wetting and drying. The temperature (85° C) and flow of carbon dioxide caused drying within 1 - 2 minutes. After each dehydration phase of 30 minutes, the samples were dispersed in 0.1 mLof 1.0 mM HC1 to maintain acidity, followed by the next dehydration cycle. Variable experimental parameters included initial pH, temperature, the time given to each cycle and the numbers of cycles. At the end of the cycle series, the samples were dissolved in 0.1 mL of water. Isolation of productsThe polymer products were isolated by standard precipitation in ethanol (2.5 X volume ethanol 100%, 1/10 volume sodium acetate 3 M pH 5.2, 1.6 jiL linear acrylamide 5 mg/mL (Fischer scientific) for 700 jiL of reaction mixtures, followed by incubation at - 20°C overnight). The pellets were consistent with polymers that behaved like RNA. Quantitative analysis was performed by UV absorbance with a NanoVue instrumentcalibrated for RNA to estimate yields of products. Depending on the conditions, typical yields ranged from 1% to 40% expressed as the fraction of the total weight of mononucleotides present, and over 55% if additional monomers were added during cycling.Characterization of productsAs described above, double-stranded polynucleotide structure was shown by ethidiumbromide, alkaline hydrolysis, RNase hydrolysation, hypochromicity, nanopore analysis andmicroscopy. Effect of monovalent cations on polymerizationWhen the HD cycles were run with monovalent salts in the reaction mixture, yields ofpolymer were dramatically increased compared to absence of salts. Furthermore, the productswere stained by ethidium bromide, an intercalating dye, suggesting that base stacking was present. Sodium, potassium and ammonium chloride all promoted synthesis of polymers containing AMP and UMP as monomers. Products ranging from 10 to 300 nucleotides with a peak around 100 mers were detected. NH4C1 had the greatest effect, but products from LiC1produced only a weak band in the gel even though the yield measured by ethanol precipitation was in the same range as NH4C1 (Table 2). The A260/A280 ratio provides an estimate of how much of the absorbance is due to polymers and how much to monomers. A ratio of 2 corresponds to RNA while a ratio of 3.4 is observed for monomers. The high ratio with LiC1 indicates that the product has relatively short strands of oligomer lacking base stacking compared with the other salts.Mixtures of AMP 10 mM + UMP 10 mM + monovalent salt 0.1 M (LiC1, KC1, NaC1 and NH4C1) in 1:1:1 volume ratio were submitted to 16 HD cycles of 30 minutes. Table 2 below shows yields of polymers synthesized and ratio A260/A280 measured by UV absorbance with a NanoVue instrument. Yields are values from duplicate samples, and were calculated as the percent by weight of the original AMP and UMP present in the mixtureTable 2. Effect of monovalent salts on polymerization.SaltYield (%)A260/A280LiC138; 423.4NaC116; 182.1KC125; 292.0NH4C134; 372.0Yields were highest with LiC1, NH4C1, KC1 and NaC1, in that order, but the LiC1product was less stained by ethidium, probably because the oligomers were shorter withdecreased base stacking.Cycling increases yield of polymersThe optimum conditions for the polymerization process were determined by performing a set of experiments using a variety of controls and conditions including thenumber of cycles, duration of the cycles, pH and temperature. The synthesis of polymers is the most efficient at high temperature (around 85 °C), at acidic pH (3) and in the presence of CO2 stream. Without wishing to be bound by any theory, the above suggests that synthesis of the ester bond is an acid catalyzed mechanism and that CO2 plays an essential role in the polymerization process. Most of the product appeared to be polymers from 10 to 300nucleotides long. Finally, the dehydration phase appeared to be essential for the polymerization process since a minimum of 30 minutes of drying at each cycle is necessary to synthesize the 300 nt species (data not shown). Role of NH4 cations in promoting polymerizationBecause NH4C1 seemed to have the greatest effect on yields of polymers, a series of further experiments were conducted. Figure 3 shows results with different ammonium salts, including ammonium phosphate, ammonium molybdate, and ammonium formate. Only the ammonium formate yielded polymers ranging from 10 to 300 nucleotides in length but inlesser amounts compared to ammonium chloride. The importance of the chemical effect of the ammonium cation in this polymerization process was also tested by substituting tetramethylammonium chloride for ammonium chloride. Fig. 14 shows polymer synthesis after 8 hours of 30 minutes HD cycles. Yields are normalized for comparison, taking the products in the presence of NH4C1 as 1.0. Salts, lane A: NH4C1; lane B: C19H42BrN; lane C:HCO2NH4 lane D: (NH4)6Mo7O244H2O; lane E: NH4H2PO4. Fig.14 shows that tetramethylammonium chloride also produced polymers ranging from 10 to 300 nucleotides in length but with lower efficiency than ammonium chloride. This suggests that NH4 might have chemical effects induced by its protons coupled to the ordering effects on the mononucleotides.Kinetics of oligomerizationThe oligomerization process in the presence of ammonium chloride follows anexponential curve, and reaches a plateau after 30 hours of wet-dry cycles with a yield of 40%(Fig. 15). Fig. 15 shows results from Mixture of AMP 10 mM + UMP 10 mM + NH4C1 0.1M (1:1:1 volume ratio) showing the total amount and yield of products over multiple cycles.Each hour has two 30 minutes cycles, so 40 hours represents 80 cycles.Control of nucleotide concentration: nucleotide feedingTo determine whether the plateau was due to exhaustion of monomers, a feeding experiment was performed in which fresh monomers were added every 2 hours (4 cycles).An enhancement of oligomerization occurred when cycling is accompanied by regular additions of monomers. A yield of 58% is obtained after 5 feeding steps (final concentration of nucleotides equal to 60 mM) whereas for the same concentration (60 mM) present at the beginning of the experiment, the yield is 37%. This means that controlling nucleotides concentration by stepwise additions enhances the polymerization process in comparison to nucleotide pooi at an equivalent concentration.The plateau can be due to an equilibrium between synthesis and hydrolysis, although degradation of nucleotides over time may also contribute. Figure 6 shows that longerproducts accumulate in later cycles. Indeed, there is an enhancement of the production of short fragments (10 and 150 nts) after few cycles, and then their presence decreases as a function of time whereas the long polymers (700 and 1000 nts) accumulate in the later cycles. Lengthening may occur either by elongation and/or by ligation of short fragments.

With pyridine; dicyclohexyl-carbodiimide In water at 50℃; for 3h; 2.6. Chemical synthesis and purification of AThTP AThTP was synthesized by condensing ThDP and AMP in pyridine in the presence of DCC. The routine procedure for the preparation of AThTP was as follows. Weighed amounts of AMP (0.55 mmol) and ThDP (0.46 mmol) were dissolved each in 0.68 ml of H2O, put in 137 ml of warmed up to 50 C pyridine and thoroughly stirred until being complete dissolved. Then 13.7 g of DCC was added and the final reaction mixture, containing 1.38 mg/ml of ThDP, 1.36 mg/ml of AMP and 96mg/ml of DCC, was let stand for 3 h at 50 C. Afterward, the reaction medium was transferred to 500 ml of absolute ethanol and the mixture was placed in a freezer at 20 C to precipitate the products. The precipitate formed was collected by centrifugation (5000 g, 10 min), dissolved in 8 ml of 5 mM Na-acetate buffer, pH 3.8, and passed through acolumn of SP Sephadex C-25 (2.5 × 20 cm) equilibrated with the same buffer (flow rate 10 cm/h). Fractions of 3 ml were collected and those ones containing AThTP were combined, adjusted to pH 7.0 with 0.5 MTris-HCl, pH 8.9, and applied to a DEAE Sephadex A-25 column (2.5 ×20 cm) equilibrated with 10 mM Tris-HCl buffer, pH 7.2. After washing the column, elution was carried out with a linear gradient of increasingNaCl concentration from 0 to 0.3 M (250 ml both in the mixing chamberand reservoir) at a flow rate of 15 cm/h. The volume of a fraction was 5ml. Then the AThTP fractions were pooled, evaporated to 1 ml and precipitated with 100 ml of absolute ethanol at 20 C. Finally, theprecipitate was collected by centrifugation (5000 g, 10 min), dissolved in 5 ml of 5 mM Na-acetate buffer, pH 3.8, and chromatographed repeatedly on the column of SP-Sephadex C-25. The fractions of AThTP peak were stored frozen at 20 C.
