Catalytic Mechanism of γ-Elimination and Michael Addition Catalyzed by Pyridoxal-5'-Phosphate-Dependent γ-Substitution Enzyme Fub7 Involved in the Biosynthesis of 5-Alkyl-pipecolic Acid.
Fub7 is a rare pyridoxal 5'-phosphate (PLP)-dependent enzyme that can subsequently catalyze the γ-elimination of O-acetyl-l-homoserine (OAH) and Michael addition with n-valeraldehyde (NVA) to synthesize 5-alkyl-pipecolic acid, which shows significant potential in synthetic chemistry. In this study, we constructed the c...
