Most of the phosphorus present in the troponin complex, which on average contains 1 mol of P/80000g, is associated with the ;37000 component' (0.6mol of P/mol). The inhibitory protein and particularly the ;37000 component', but not the calcium-binding protein, were phosphorylated when incubated with phosphorylase b kinase and [gamma-(32)P]ATP.
肌钙蛋白复合体中存在的大部分磷(平均每80000克含1摩尔磷)与“37000组分”(每摩尔含0.6摩尔磷)相关。当与磷酸化酶b激酶和[γ-(32)P]ATP一起温育时,抑制蛋白,特别是“37000组分”,而不是钙结合蛋白,会发生磷酸化。
