THE HYDROLYSIS OF DIPEPTIDES AND AMINOACYL NAPHTHYLAMIDES BY THE HUMAN SEMINAL PLASMA

Abstract
High dipeptidase and aminopeptidase activity is present in human seminal plasma. The two activities can be easily and clearly separated from each other by chromatographic procedures. Each of the three dipeptidase fractions has characteristic substrate specificity but is not affected by divalent metals. The seminal aminopeptidase activity is inhibited by EDTA and activated by cobalt.
