Largomycin, an antibiotic and antitumor protein, purified from the culture broth ofStreptomyces pluricolorescens, displayed specific proteolytic activity. Pure largomycin did not degrade a number of substrates commonly used for detection of aminopeptidase, endopeptidase and carboxypeptidase activity. Pure largomycin degraded angiotensin II, bradykinin, a few dipeptides and a number of proteins of KB cell plasma membranes. The biological activity and the proteolytic activity of largomycin showed similar temperature-dependent patterns, suggesting that one protein in responsible for both activities. The apoprotein of largomycin, which did not show antibiotic activity, contained the proteolytic activity.
