Pancreatic islet cytosol contains a calcium-calmodulin dependent protein kinase that can mediate the phosphorylation of an endogenous protein that has an Mr of 57 000, as well as exogenous muscle pyruvate kinase (subunit Mr, 57 000). EGTA and trifluoperazine decreased the phosphorylation. Alkaline i
