Bovine heart peak II calcium-dependent protease was capable of hydrolyzing its specific inhibitor protein at high molar ratios of protease to inhibitor. The proteolysis was inhibited by leupeptin and required millimolar calcium. Thus, it appeared to be attributable to the calcium-dependent protease and not to possible contaminating proteases in the purified preparations of inhibitor or calcium-dependent protease. Incubation of the purified inhibitor with the calcium-dependent protease produced a discrete pattern of inhibitor fragments on Western blots developed with an inhibitor-specific monoclonal antibody. Traces of similar or identical lower molecular weight immunoreactive material could be observed in Western blots of bovine heart extracts, and the immunoreactivity present as these lower molecular weight forms could be increased by incubation of the extracts with calcium ion. These results suggest that the inhibitor can be proteolyzed to low molecular weight forms which can be detected in cardiac tissue extracts, and that calcium-dependent protease(s) may be responsible for this phenomenon.
