Localization of Escherichia coli rpoC mutations that affect RNA polymerase assembly and activity at high temperature.
نویسندگان
چکیده
We localized five rpoC (beta') mutations affecting Escherichia coli RNA polymerase assembly. The Ts4, XH56, and R120 mutations changed beta' residues conserved throughout eubacteria; the JE10092 mutation occurred in the hypervariable region; rpoC1 (TsX) changed a universally conserved residue and corresponds to yeast rpb1-1. Thus, distinct, predominantly conserved beta' residues participate in interactions holding RNA polymerase together.

Escherichia coli rpoC397 encodes a temperature-sensitive C-terminal frameshift in the beta' subunit of RNA polymerase that blocks growth of bacteriophage P2.
Escherichia coli 397c is temperature sensitive for growth at 43.5 degrees C and unable to plate bacteriophage P2 at 33 degrees C. The mutation conferring these phenotypes was mapped to the rpoC gene. RNA synthesis is temperature sensitive in the mutant strain, and the beta' subunit of RNA polymerase isolated from this strain exhibits increased electrophoretic mobility. DNA sequence analysis rev...
متن کاملEscherichia coli RNA polymerase is the target of the cyclopeptide antibiotic microcin J25.
Escherichia coli microcin J25 (MccJ25) is a plasmid-encoded, cyclic peptide antibiotic consisting of 21 unmodified amino acid residues. It is primarily active on gram-negative bacteria related to the producer strain, inducing cell filamentation in an SOS-independent way. A mutation causing resistance to MccJ25 was isolated. Genetic analysis indicated that it resided in the rpoC gene, encoding t...

A series of inhibitors with a squaramide core was synthesized following its discovery in a high-throughput screen for novel inhibitors of a transcription-coupled translation assay using Escherichia coli S30 extracts. The inhibitors were inactive when the plasmid substrate was replaced with mRNA, suggesting they interfered with transcription. This was confirmed by their inhibition of purified E....
متن کاملEffects of rifampicin resistant rpoB mutations on antitermination and interaction with nusA in Escherichia coli.
Rifampicin resistant (Rifr mutations map in the rpoB gene encoding the beta subunit of Escherichia coli RNA polymerase. We have used our collection of 17 sequenced Rifr mutations to investigate the involvement of E. coli RNA polymerase in the antitermination systems enhancing expression of delayed early lambda genes or stable RNA. We have found that Rifr mutations affect both lambda N-mediated ...
متن کاملStudy of Mutations in the DNA gyrase gyrA Gene of Escherichia coli
Quinolones are a large and widely consumed class of synthetic drugs. Expanded-spectrum quinolones, like ciprofloxacin are highly effective against Gram-negative bacteria, especially Escherichia coli. In E. coli the major target for quinolones is DNA gyrase. This enzyme is composed of two subunits, GyrA and GyrB encoding by gyrA and gyrB, respectively. Mutations in either of these genes cause qu...
