WebChymotrypsin is a member of a family of enzymes that cleave peptide bonds through the action of an active site serine (the serine proteases) [15]. This family includes the … WebpH in which chymotrypsin acts is 7.8 – 8.0. There are two main forms of chymotrypsin such as chymotrypsin A and chymotrypsin B and they slightly differ in there structural and proteolytic characteristics. The active site of chymotrypsin contains a catalytic triad and is composed of Histidine (H57), Aspartic acid (D102) and Serine (S195).

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. WebV1891) is a serine protease that preferentially cleaves at the C-terminus of alanine, valine, serine, glycine, leucine or isoleucine residues. Elastase activity is optimal at pH 9.0. Pepsin (Cat.# V1959) preferentially cleaves at the C-terminus of phenylalanine, leucine, tyrosine and tryptophan residues. Pepsin activity is optimal at pH 1.0–3.0.
