Trypsin cleaves a polypeptide backbone at the C-terminal side of Arg or Lys residues, whereas chymotrypsin cleaves after aromatic residues. A polypeptide was treated with trypsin to generate a series of fragments of the following sequences: Gly-Gly-Ile-Arg Ser-Phe-Leu-Gly Trp-Ala-Ala-Pro-Lys Ala-Glu-Glu-Gly-Leu-Arg And the same polypeptide was treated with chymotrypsin to generate the following fragments: Leu-Gly Ala-Glu-Glu-Gly-Leu-Arg-Trp Ala-Ala-Pro-Lys-Gly-Gly-Ile-Arg-Ser-Phe Assemble the protein sequence.
