expression of mutant enzyme L476Q and M365L/L461S in Escherichia coli Pseudomonas putida

Protein Variants

Protein Variants Comment Organism
L476Q mutant enzyme selectively catalyzes the formation of enantiopure (S)-2-hydroxy-1-(2-methylphenyl)propan-1-one with excellent yield, a reaction which is only poorly catalyzed by the wild-type enzyme. Vmax and Km-value for decraboxylation of benzoylformate are not effected Pseudomonas putida
M365L/L461S mutant enzyme selectively catalyzes the formation of enantiopure (S)-2-hydroxy-1-(2-methylphenyl)propan-1-one with excellent yield, a reaction which is only poorly catalyzed by the wild-type enzyme. Mutant enzyme retains only 9% of the wild-type BFD carboligase activity. Decrease in Vmax value as well as an increase in the Km-value for decarboxylation of benzoylformate by mutant enzyme compared to that of wild-type enzyme Pseudomonas putida
