Cysteine protease enzyme
WebTo properly function, proteases must preferentially cleave their target substrates in the presence of other proteins. While many factors impact protease substrate selection, one of the key aspects is the complementary nature of the enzyme-active site with the residues surrounding the cleaved bond in the substrate.

WebAug 23, 2024 · Cysteine proteases (also known as thiol proteases) catalyze the breakdown of proteins by cleaving peptide bonds using a nucleophilic thiol from a cysteine (Figure 4.63). The cysteine is typically found in a catalytic dyad or triad also involving histidine and (sometimes) aspartic acid (very much like serine proteases).
WebThese proteases can be classified into cysteine (n = 28), serine (n = 21), threonine (n = 14), asparagine (n = 7), and metallopeptidases (n = 19), which, in turn, are assigned to a total of 38 peptidase families. ...
