The secondary structures of cow and sheep kappa-caseins were established according to the predictive rules of Chou and Fasman. The diagrams derived from this treatment allowed us to study the chymosin sensitive bond (milk-clotting process), as well as the glycosylation and phosphorylation sites, found to be situated in beta-turns. Despite a high variability between the primary structures of the COOH-terminal part (caseinoglycopeptide) of cow, sheep, and also other caseins, the secondary structures of the biologically important sites were found to be conserved.
根据Chou和Fasman的预测规则确定了牛和羊κ-酪蛋白的二级结构。从该处理得出的图表使我们能够研究凝乳酶敏感键(凝乳过程)以及糖基化和磷酸化位点,发现它们位于β-转角处。尽管牛、羊以及其他酪蛋白的COOH末端部分(酪蛋白糖肽)的一级结构存在很大差异,但发现生物学重要位点的二级结构是保守的。
