title: Protein kinase activities in mammalian blood fluid.
abstract: Two protein kinase activities, one specific for phosvitin and another specific for histone, were detected in serum and plasma of calf as well as of human blood after precipitation with ammonium sulfate (40%) and chromatography on DEAE-Sephacel. The enzymes were separated by chromatography on phosphocellulose. The histone kinase is not related to the cyclic AMP-dependent protein kinase; it may derive at least partly from damaged cells. The phosvitin kinase activity carries characteristics of the so called casein kinase type II similar to that present at the surface of cells including blood cells.
