Enzymatic cleavage: trypsin is most commonly used. It hydrolyses the peptide bonds containing lysine or arginine on the carbonyl (-C=0) side of peptide linkage. Chemical cleavage: Cyanogen bromide (CNBr) is commonly used to split polypeptides into smaller fragments. CNBr specifically splits peptide bonds, the carbonyl side of which is contributed by the amino acid methionine.
