Abstract

A process for producing efficiently glutamic acid derivatives (including salts thereof) such as monatin is described. This process entails converting a substituted α-keto acid of formula (1) into a glutamic acid derivative of formula (2) in the presence of an enzyme catalyzing conversion of the same.
