We thus, achieved a freat success in the separation of dipeptidase from aminopolypeptidase and proteinase as well as in the separation of aminopolypeptidase free from dipeptidase and proteinase. The specific activity (C) of the former (leucylglycine hydrolusis) was 7000 and that of the latter (leucylglycine hydrolysis) 22000.1 aAKATSUKA, T. tJapan: Bull. Agr. Chem.
