Cleavage proceeds by a four-stage mechanism. The third stage is an hydrolysis reaction that cleaves the peptide chain. At the end of this stage, the carboxyl group of the former methionine becomes part of a lactone (cyclic ester) ring. Draw curved arrows for the first step of this stage. -NHCHÖNHCH-C-OH CH₂ CH₂-OH + {} H₂NCC- R'
