Summary

The proteolytic specificity of chymosin (EC 3.4.23.4) on bovine αs1-casein at 30°C in phosphate buffer, pH 6·5 and at pH 5·2 in the presence of 5% (w/v) NaCl was investigated. Peptides (pH 4·6-soluble) were isolated by reversed-phase HPLC and identified from their amino acid sequence; the identity of some peptides was confirmed by mass spectrometry and/or amino acid composition. The small peptides produced at pH 6·5 were Arg1–Phe23, Phe24–Phe28, Phe24–Leu40(?), Phe150–Phe153, Phe150–Leu156, Tyr154–Tyr159, Tyr154–Trp164, Asp157–Trp164 and Tyr165–Trp199. The same peptides, except Tyr154–Trp164, were produced at pH 5·2 in the presence of NaCl and, in addition, the peptides Arg1–Leu11, Phe24–Phe32, Lys102–Leu142, Ala143-Leu149 and Tyr165-Phe179. The rates of production of individual peptides differed under the two conditions studied but Arg1-Phe23 and Tyr165–Trp199 were the first and second peptides produced under both conditions. Pathways are proposed to interpret the proteolysis of αs1-casein in solution under the conditions of this study.
