✦ Synopsis

An E. coli mutant rpoA109 unable to support the growth of phage P2 produces DNA-dependent RNA polymerase with an altered alpha subunit. Histidine is substituted for leucine in one tryptic peptide from the mutant alpha subunit. The existence of only one rpoA gene within the E. coli chromosome is indicated.
