Abstract: The prenylated-flavin mononucleotide-dependent decarboxylases (also known as UbiD-like enzymes) are the most recently discovered family of decarboxylases. The modified flavin facilitates the decarboxylation of unsaturated carboxylic acids through a novel mechanism involving 1,3-dipolar cyclo-addition chemistry. UbiD-like enzymes have attracted considerable interest for biocatalysis applications due to their ability to catalyse (de)carboxylation reactions on a broad range of aromatic substrates at otherwise unreactive carbon centres. There are now ∼35[thin space (1/6-em)]000 protein sequences annotated as hypothetical UbiD-like enzymes. Sequence similarity network analyses of the UbiD protein family suggests that there are likely dozens of distinct decarboxylase enzymes represented within this family. Furthermore, many of the enzymes so far characterized can decarboxylate a broad range of substrates. Here we describe a strategy to identify potential substrates of UbiD-like enzymes based on detecting enzyme-catalysed solvent deuterium exchange into potential substrates. Using ferulic acid decarboxylase (FDC) as a model system, we tested a diverse range of aromatic and heterocyclic molecules for their ability to undergo enzyme-catalysed H/D exchange in deuterated buffer. We found that FDC catalyses H/D exchange, albeit at generally very low levels, into a wide range of small, aromatic molecules that have little resemblance to its physiological substrate. In contrast, the sub-set of aromatic carboxylic acids that are substrates for FDC-catalysed decarboxylation is much smaller. We discuss the implications of these findings for screening uncharacterized UbiD-like enzymes for novel (de)carboxylase activity.

79% | at 295℃; for 1h; | General procedure: Following the amide intermediate Preparation Example A. The reaction vessel is closed (when the amide intermediate has a boiling point at normal pressure equal to or lower than the reaction temperature TB described below) or the reaction vessel is kept open (when the amide intermediate has a boiling point higher than the normal pressure When the reaction temperature is TB), stirring is continued (600 r/min), the reaction temperature is changed to TB, and after the reaction temperature TB is maintained for TD hours, the reaction is substantially completed. Then, the reaction vessel was sealed and connected to a vacuum pump so that the degree of vacuum in the reaction vessel reached 20-50 mbar (according to the type of nitrile product) and the distillate was used as the nitrile product. The yield of the nitrile product was calculated and sampled for nuclear magnetic resonance and elemental analysis to characterize the nitrile product obtained. Specific reaction conditions and characterization results are shown in Tables A-7, A-8, A-9, A-10, A-11 and A-12 below. These characterization results show that the nitrile product obtained has an extremely high purity (above 99%).In these nitrile product preparation examples, 10 g of phosphorus pentaoxide is preferably added to the reaction vessel as a catalyst at one stage, optionally at the beginning of the reaction. |

After addition of the hydride is complete, the reaction is allowed to warm to room temperature and is stirred for 30 minutes. The thickened reaction mixture is cooled to 0 to 5 C. and is then added dropwise over 30 minutes to a solution of 30 grams of p-pivaloylbenzoyl chloride in 50 ml of dry THF. The resulting solution is stirred for 15 minutes at 0 to 5 C. and is then quenched with 150 ml of saturated ammonium chloride solution. The THF phase is decanted off, and the aqueous phase is extracted with ethyl acetate. The ethyl acetate extract is combined with the THF phase, dried with magnesium sulfate, filtered, and then evaporated almost to dryness. The resulting solids are triturated with ether, and the white crystals obtained are filtered, washed with ether and dried to yield the title product (m.p. 137-138 C.).

Beginning after one hour, additional 2 mL aliquots of 88% formic acid are added at approximately 30 minute intervals until the phenethylamine is consumed, as monitored by gas chromatography. The reaction mixture is distilled (using a Dean-Stark trap) at approximately 200 C. for approximately 45 minutes after which it is allowed to cool to room temperature. A 250 mL round bottom flask equipped with stir bar, reflux condenser, and an addition funnel is charged with phosphorus pentoxide (7.07 g) and polyphosphoric acid in a 10.5:1 weight ratio.

The cooled, crude phenethylformamide prepared as described above is added dropwise to this mixture. On complete addition the reaction is heated and stirred at approximately 170 C. overnight. The mixture is cooled to room temperature and diluted with water (300 mL), washed with diethyl ether (150 mL) and cooled in an acetone/dry ice bath while the pH is adjusted to 9 with saturated potassium hydroxide. The aqueous solution is extracted with ether (3*150 mL) and the pooled organics are dried over magnesium sulfate, filtered, and concentrated under reduced pressure to yield an oil that is further purified via Kugelrohr distillation (70 C., 1 mm Hg) to give the compound of formula 2. |

Solid NBA (1-8 equiv) was added in one portion and the heterogeneous mixture was stirred, while the temperature gradually attained r.t. The reaction progress was monitored by TLC, requiring 24-48 h for completion. The reaction mixture was added to 10% aqueous Na2S2O5 (2 volumes) and concentrated on a rotary evaporator (30 C, 30 min). The liquid residue was diluted with 5% aqueous NaOH (15 volumes) and extracted with CH2Cl2 (3 × 8 volumes). The combined extracts were concentrated on a rotary evaporator and vacuum-dried (0.2 mmHg, 40 C, 1 h). Further purification, when necessary, was achieved by dry-column flash chromatography, using the solvent gradient as indicated. When BnOH was used instead of MeOH, the procedure was modified as follows: After reaction completion, the mixture was diluted with CH2Cl2(25 volumes) and extracted successively with 10% aqueous Na2S2O5 (2 volumes) and 5% aqueous NaOH (15 volumes). The organic layer was concentrated on a rotary evaporator and the excess BnOH was removed under reduced pressure (0.2 mm Hg, 80 C, 45 min).
