Abstract
Two cyclic nucleotide-independent protein kinases (ATP:protein phosphotransferase, EC 2.7.1.37) have been purified to homogeneity from rat liver nuclei. While these enzymes have many similar catalytic properties (preference for acid rather than basic proteins), they differ in molecular weight and subunit composition. Protein kinase NII will utilize ATP and GTP as phosphate donors while protein kinase NI will only effectively use ATP. Both enzymes reveal an unusual activation by Fe2+.Entities:
