Abstract
Recombinant cells and an improved method utilizing them is disclosed for the preparation of an optically pure, L-amino acid from its D and D,L isomer forms. The process utilizes cell cultures that possess high aminotransferase activity that exhibits moderate selectivity in the conversion of D and L amino acids to their respective 2-keto acids as well as absolute stereospecificity in the conversion of the 2-keto acids to the L isomer alone.
