Genetic and physiological studies of Bacillus subtilis sigma A mutants defective in promoter melting.
The Bacillus subtilis sigA gene encodes the primary sigma factor of RNA polymerase and is essential for cell growth. We have mutated conserved region 2.3 of the sigma A protein to substitute each of seven aromatic amino acids with alanine. Several of these aromatic amino acids are proposed to form a...
