The enzyme trypsin is specific for peptide bonds of:
Basic amino acids
Acidic amino acids
Aromatic amino acids
Next to small amino acid residues
Ans. A. Basic amino acidsTrypsin is an endopeptidase which cleave protein chains at internal peptidebonds, but each preferentially hydrolyses bonds adjacent to a particular type of amino acid residue. Trypsin cuts just next to basic residues (lysine or arginine); chymotrypsin cuts next to aromatic residues (phenylalanine, tyrosine or tryptophan).
