title: [Similar organization of beta,beta'-subunit RNA-polymerase genes and adjacent ribosomal protein genes in Enterobacteriaceae and Pseudomonas putida].
abstract: The genes coding for the RNA-polymerase beta,beta'-subunits and adjacent ribosomal protein genes in Escherichia coli, Salmonella typhimurium, Shigella flexneri, Serratia marcescens, Proteus mirabilis and Pseudomonas putida are compared by the Southern hybridization procedure. In all the species studied close clustering of the genes rplKAJL and rpoBC is demonstrated. Preliminary physical maps for these genes in S. typhimurium, S. flexneri, S. marcescens and P. mirabilis are proposed. Rifampicin is shown to stimulate the beta,beta'-subunit synthesis in all the species studied, suggesting the existence of attenuators localized in front of the rpoBC genes. The similar arrangement of the genes rplKAJLrpoBC in a number of bacterial species is proposed to be due to common mechanisms of their coordinate expression.
