WebFurthermore, the increasing negative charge in the reaction's transition state cannot any longer be stabilized by the serine side chain. As a result, the catalytic triad would be unable to function as it once did, and the enzyme's reaction rate would be reduced. 1.

"WebThe hydrolysis of a peptide bond is helped along by two common means, and those two means are with the help of strong acids or with proteolytic enzymes. So when we use strong acids, we call this acid hydrolysis. And acid hydrolysis, when combined with heat, is a nonspecific way of cleaving peptide bonds. " - Chymotrypsin reaction mechanism
