Abstrakt: An endopeptidase isolated from bovine kidney displays high affinity and selectivity for the Ser-Phe bond located in the C-terminal region of atrial peptides. Enzymatic activity converts APIII and APII to the less active peptide API. This peptidase is inhibited by both metal chelators and sulfhydryl-reactive agents, suggesting both a tightly bound metal and a cysteine residue are important for enzymatic activity. This enzyme may be important for the processing and/or degradation of atrial peptides.
