Phosphorylation of the "37000 component" of the troponin complex (troponin-t).
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.
