Chemical Structure of a Modification of the Escherichia coli Ribonucleic Acid Polymerase α Polypeptides Induced by Bacteriophage T4 Infection

The cr-polypeptides of Escherichia coli RNA polymerase are known to be chemically modified within 4 min after infection by bacteriophage Tq.This paper reports a crude system derived from T1-infected E. coli which will modify the cr-polypeptides of purified E. coli RNA polymerase
