WebCaspases are a family of cysteine proteases, which are phylogenetically conserved throughout metazoans and serve many different roles. Mammalian caspases are categorized into two functional groups, those involved in immunity and those that facilitate apoptotic cell death. WebMar 3, 2024 · Introduction. Tumor-associated proteolysis is considered a key driver of tumor invasion and metastasis. It involves proteases of all four major catalytic classes, which are represented by the serine, cysteine, and aspartic proteases and metalloproteases. 1−4 A pivotal function of these protein-degrading enzymes in tumor progression is believed to …
WebThe serine proteases are probably the best characterized. This class of proteases includes trypsin, chymotrypsin and elastase. The cysteine protease class includes papain, calpain and lysosomal cathepsins. … WebNational Center for Biotechnology Information
WebViral proteases may use different catalytic mechanisms involving either serine, cysteine or aspartic acid residues to attack the scissile peptide bond. This bond is often located within conserved sequence motifs … Webcysteine.

WebAn interesting feature of this protease is its broad specificity for peptide bonds, allowing a high degree of protein hydrolysis to be achieved. But this enzyme, like other cysteine proteases, has a preference for an amino acid containing a large hydrophobic side chain at position P2 and does not accept Val at P1' [53].
