Abstrakt: This report describes the enzyme-catalyzed synthesis, characterization, and chromatographic separation of N-(carboxymethyl)-L-lysine and N-(carboxymethyl)-L-ornithine. The two N-(carboxyalkyl)amino acids are formed via a reductive condensation between glyoxylate and the ε- or δ-amino groups of lysine and ornithine, respectively. Both reactions are catalyzed by the NADPH-dependent enzyme, N-(carboxyethyl)ornithine synthase [EC 1.5.1.24], found in some strains of the lactic acid bacterium Lactococcus lactis subsp. lactis.
