| Abstract: | Chicken pepsinogen was incubated at pH2.5 with pepstatin. The zymogen activated itself by a sequential mechanism and an intact peptide derived from residues 1-26 in the protein was released in the first step. This peptide was found to inhibit the milk-clotting activities of pig and chicken pepsins and calf chymosin but to different extents. |
