Abstract

A process for making natural and unnatural amino acids which comprises reacting a first amino acid, a keto acid and a transaminase enzyme under conditions appropriate to produce a second amino acid and pyruvate; reacting the pyruvate with acetolactate synthase under conditions appropriate to produce a compound that does not react with the transaminase enzyme and separating the second amino acid.
