Studies on the Enzymatic Resolution (V). Enzymatic Resolution of DL-Lysine (2)

Abstract

The advantageous resolution procedure of DL-lysine previously reported, consisting of the enzymatic hydrolysis of ε-benzoyl-α-acetyl-DL-lysine with mold enzyme preparation was innovated. Susceptibility of ε-benzoyl-α-acetyl-DL-lysine towards various enzyme preparations such as kidney, pancreas extracts, renal acylase and carboxy-peptidase, was investigated. As a result, it was found that although the substrate was readily hydrolyzed by the mold enzyme preparations, the other enzyme preparations showed, almost no, if any, hydrolytic activity.
