This enzyme exhibits cysteine protease activity with broad endopeptidase specificity. Cathepsin V is a human lysosomal cysteine endopeptidase. Asparagine endopeptidase is synthesized as an inactive zymogen. A metalloendopeptidase is an enzyme that functions as a metalloproteinase endopeptidase. Omapatrilat inhibits angiotensin-converting enzyme and neutral endopeptidase and effectively reduces hypertension. It is a serine endopeptidase (protease group S1, PA clan). It is the type serine endopeptidase of MEROPS family S8. Neutral endopeptidase (NEP) also known as neprilysin is the enzyme that metabolizes natriuretic peptides. It inhibits both neprilysin (neutral endopeptidase, NEP) and angiotensin-converting enzyme (ACE). BNP is cleared by binding to natriuretic peptide receptors (NPRs) and neutral endopeptidase (NEP). It is an aspartic endopeptidase belonging to MEROPS A1 family. S2P endopeptidase () is an enzyme. Other studies have implicated neutral endopeptidase and cationic bovine serum albumin as antigens. Baicalin is a known prolyl endopeptidase inhibitor. Pepsin is an endopeptidase that breaks down proteins into smaller amino acids.
