Abstract

Bovine serum albumin from a number of commercial sources were screened for the presence or absence of peptidase contamination. Peptidase activity was monitored using various peptides as substrates. Two commercial preparations were found to have peptidase activity, and the enzyme was identified, on the basis of its substrate specificity, as prolidase (EC 3.4.14.9). The contaminating activity was in the order of 3-4 units/g albumin.
