H₂O :Ö-H H nichonich_8_om CH₂ CH₂-OH CH₂-S-CH3 Proteins can be cleaved specifically at the amide bond on the carboxyl side of methionine residues by reaction with cyanogen bromide (above). 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.
