Abstract
A peptide with C-terminal proline amide is produced by reacting in aqueous solution a protein substrate having C-terminal prolyl-leucine, prolyl-isoleucine, prolyl-valine, or prolyl-phenylalanine with carboxypeptidase Y in the presence of ammonia. The ammonia is preferably generated by the aqueous reaction of an ammonium salt and an alkali. An example of the peptide product is human calcitonin.
