Abstract The proteolytic specificity of chicken cathepsin L was studied using bovine β-casein as substrate. The peptide mixtures obtained after various times of hydrolysis were separated by RP-HPLC and ten peptides were identified. Chicken cathepsin L accepts proline residues in all positions except P 1 ′ . Looking at the amino acid residues on the amino side of the scissile bond we found three times the Tyr-Pro pair at P 1 ′ –P 2 ′ positions and that the S 1 ′ subsite can interact with modified amino acids such as phosphoserine.
