A gene from Escherichia coli affecting the sigma subunit of RNA polymerase.

PMCID: PMC431020  PMID: 325556

Abstract

The RNA polymerase sigma subunits of Escherichia coli K, E. coli C, and Salmonella typhimurium can be resolved by electrophoresis. Using this technique, we have analyzed Salmonella strains carrying F' plasmids from E. coli K in order to map the gene for the sigma factor. Partial diploid analyses show the location of the sigma gene at 62-66 min on the E. coli genetic map. This gene is cotransducible with toIC and dnaG, at 66 min.
