Abstract
A histone-type protein kinase (EC 2.7.1.37) has been partially purified (320-fold) from the crude extracts of soybean hypocotyls by means of a combination of gel filtration and anion exchange procedures. The purified enzyme fraction is devoid of the activities of phosphoprotein phosphatase (EC 3.1.3.16), histone protease, and casein (or phosvitin)-type kinase. The soybean histone kinase uses ATP to phosphorylate specifically lysine-rich histone H1 from either pea seedlings or calf thymus.Keywords
