Abstract excerpt

The composition of RNA polymerase sigma subunits was analyzed for stock strains of Escherichia coli K-12 W3110 in Japan. Heterogeneity was discovered with respect to two sigma subunits, sigma28 (sigmaF, the rpoF gene product) and sigma38 (sigmaS, the rpoS gene product). Five different types of W3...
