Webcatalysis is observed in the mechanism of the chymotrypsin reaction. D. pH affects enzymatic rates The solution pH affects the ionization states of amino acids within proteins and enzymes (just as it affects ionizable groups in free amino acids); when the affected aa are involved in catalysis, the activity of the enzyme is affected.

WebHowever, both trypsin-->elastase and chymotrypsin-->trypsin conversion experiments carried out according to the complex model resulted in non-specific proteases with low catalytic activity. Chymotrypsin used in the latter studies was of B-type, containing an Ala residue at position 226. Trypsins, however, contain a conserved Gly at this site. WebReaction Mechanism • Hydrolysis by chymotrypsin is a 2-step process • Step 1: serine reacts with substrate to form covalent ES complex • Step 2: release of products from ES …
