Exopeptidases remove the terminal amino acids from the protein chain and endopeptidases attack an internal peptide bond, as in trypsin, chymotrypsin, pepsin, elastase and papain. The PSA (KLK3 ...

MMPs are a family of related zinc-dependent endopeptidases capable of degrading all extracellular matrix components, playing a major role in extracellular matrix remodeling. Finally, proteolytic ...

Depending on the bond they cleave, these enzymes are classified as N-acetylmuramidases, N-acetylglucosaminidases, N-acetylmuramoyl L-alanine amidases, endopeptidases or carboxypeptidases (Fig. 2). In ...
