Modification of RNA polymerase from Escherichia coli by pre-early gene products of bacteriophage T5.
RNA polymerase from cells of Escherichia coli infected with T5 were recovered as a complex with two pre-early phage-coded polypeptides, the 60,000-dalton product of gene A1 and a previously reported 11,000-dalton polypeptide. This RNA polymerase complex had altered transcriptional specificity, in that it transcribed pre-early genes less efficiently than it did early genes.
