We have analyzed some chemical properties of the sigma subunit of RNA polymerase from the sigma mutants: rpoD1 (Gross et al., 1978), rpoD2 (formerly known as alt-1) (Silverstone et al., 1972; Travers et al., 1978), and rpoD800 (Gross et al., 1979). Each of the three mutants is located at about 66 mi

A mutant of Escherichia coli K12 is described in which sigma and alpha subunits of the DNA-dependent RNA polymerase (EC 2.7.7.6) are produced at the rates much higher than in the normal strain. The rate of synthesis for sigma subunit was found to be at least 10-times higher, though the rapid degrada
