Definition

ChEBI: Leupeptin is a tripeptide composed of N-acetylleucyl, leucyl and argininal residues joined in sequenceby peptide linkages. It is an inhibitor of the calpains, a family of calcium-activated proteases which promote cell death. It has a role as a serine protease inhibitor, a bacterial metabolite, a cathepsin B inhibitor, a calpain inhibitor and an EC 3.4.21.4 (trypsin) inhibitor. It is a tripeptide and an aldehyde. It is a conjugate base of a leupeptin(1+).
