The effects of Escherichia coli RNA polymerase and its subassemblies and subunits on the in vitro synthesis of beta subunit directed by DNA from a lambda transducing phage lambdadrif+-6 were investigated. This phage carries the structural gene (rpoB) for beta subunit as well as the genes for EF (translation elongation factor)-Tu, some ribosomal proteins, and stable RNAs of the E. coli chromosome. Among the RNA polymerase proteins examined, the two oligomers, holoenzyme and alpha2beta complex, repressed the synthesis of only the beta subunit but not of other proteins encoded by the phage DNA. The results indicate that the expression of at least the betabeta' (rpoBC) operon is under autogenous regulation, in which both holoenzyme and alpha2beta complex function as regulatory molecules with repressor activity.
