Five membrane peptidase activities have been identified on cultured human osteoblast-like cells. These consisted of the four exopeptidases aminopeptidase-A, aminopeptidase-N, aminopeptidase-W and carboxypeptidase-M, and the endopeptidase, endopeptidase-24.11. The presence of endopeptidase-24.11 was confirmed immunochemically by immunofluorescent staining and by enzyme-linked

The enzyme responsible for the conversion of exogenous big endothelin-1 to endothelin-1 by porcine coronary arterial smooth muscle has been shown to be a metalloprotease. The potencies of eight metalloprotease inhibitors for this endothelin-converting enzyme were determined. CGS 25015, CGS
