Abstract
A deoxyribonucleoprotein (DNP) complex has been isolated from Escherichia coli cells by chromatography on Sephadex G-200. The DNP complex contains phosphoproteins and the content of phosphorus bound to the DNP protein is 3 times higher than in cytoplasmic proteins not bound to DNA. These results have been confirmed by in vivo (32-P-KH2PO4) and in vitro (32-P-ATP) phosphorylation of E. coli DNA-binding proteins isolated by chromatography on DNA--cellulose.
