In the first (аcylаtiоn) step оf chymоtrypsin cаtalysis, His57 functions as a(n) [word1] by abstracting a proton from Ser195, while Asp102 stabilizes the resulting [word2] charge on histidine. Formation of the acyl–enzyme intermediate involves cleavage of the peptide bond and release of the [word3] fragment. During deacylation, His57 again acts as a [word4] catalyst to activate [word5] for nucleophilic attack, leading to regeneration of the free enzyme.
