WebOct 31, 2024 · Chymotrypsin, a protease, is an enzyme that cleaves the carbonyl side of certain peptide bonds by both general acid-base catalysis, but primarily covalent catalysis. In this mechanism, a nucleophile becomes covalently attached to a substrate in a transition state with an acyl-enzyme. WebMar 6, 2024 · Found in our digestive system, chymotrypsin’s catalytic activity is cleaving peptide bonds in proteins and it uses the side chain of a serine in its mechanism of catalysis. Many other protein-cutting enzymes employ a very similar mechanism and they are known collectively as serine proteases (Figure 4.52).

WebSerine proteases (or serine endopeptidases) are enzymes that cleave peptide bonds in proteins. Serine serves as the nucleophilic amino acid at the (enzyme's) active site. They are found ubiquitously in both eukaryotes and prokaryotes.Serine proteases fall into two broad categories based on their structure: chymotrypsin-like (trypsin-like) or subtilisin-like.
