An inhibitor of colicin B excreted into the culture media by E. coli strains, and hyperproduced by exb mutants, is shown to be the iron chelator enterochelin (= enterobactin). Production of the inhibitor by E. coli exb + is regulated by the concentra

Erwinia carotovora RNA polymerase consists of the holoenzyme structure sigma 2 beta beta' sigma as found in Escherichia coli and other bacteria. E. carotovora RNA polymerase can synthesize RNA using lambda, T7 of T4 DNA as templates; however, it is t

Adsorption of colicin B to a sensitive strain of Escherichia coli results in rapid cessation of deoxyribonucleic acid, ribonucleic acid, and protein synthesis. Some classes of mutants insensitive to colicin B hyperexcrete a colicin inhibitor into the

Mutants exb of Escherichia coli are insensitive to colicin B and excrete into their culture media a material that inhibits colicin activity and that appears to be the bacterial lipopolysaccharide.
