4.1.2.38 A28S mutant shows decarboxylase activity towards 2-keto acids 678578 4.1.2.38 A28S point mutation converts BAL into a true benzoylformate decarboxylase. Km value for (R)-benzoin is virtually identical to that of the wild-type enzyme but whose kcat value is reduced ca. 10fold. Can decarboxylate benzoylformate, has a substrate spectrum comparable to that of benzoylformate decarboxylase, albeit with reduced activity. Methyl benzoylphosphonate and benzoylphosphonate act as competitive inhibitors in a time- and concentration-dependent manner 704205 4.1.2.38 A480I reduced lyase activity 678578 4.1.2.38 F484I reduced lyase activity 678578 4.1.2.38 H286A reduced lyase activity 678578 4.1.2.38 H29A the mutant shows 2.7% of wild type activity 747990 4.1.2.38 H29A the role of His29 in cofactor activation and catalysis is delineated 690982 4.1.2.38 Q112A/E393A/S416G/T479A variant with larger but less polar binding site -, 762916 4.1.2.38 Q112L/E393Y/S416G/T479F variant with binding site matched to Pseudomonas fluorescens enzyme -, 762916 4.1.2.38 W163A the role of Trp163 in cofactor activation and catalysis is delineated 690982
