ABSTRACT

Disclosed is a method for production of an optically active biphenylalanine compound represented by the formula (2): (wherein, R2 is a protective group of an amino group, and R3 and R4 are each independently a hydrogen atom, etc.) or a salt thereof and an optically active biphenylalanine ester compound represented by the formula (3): (wherein, R1 is an alkyl group, etc.) wherein the method comprises hydrolyzing a biphenylalanine ester compound represented by the formula (1): with a protease produced by a microorganism belonging to Bacillus sp. in the presence of at least one alkali selected from an alkali metal hydroxide and an alkaline earth metal hydroxide.
