sigma E changed to sigma B specificity by amino acid substitutions in its -10 binding region.

Journal of bacteriology - 1 Nov 1995

Tatti K M, Moran C P

Abstract excerpt

The association of a sigma factor (sigma) with RNA polymerase in bacteria determines its specificity of promoter utilization. To identify amino acid residues in sigma E from Bacillus subtilis that determine the specificity of its interaction with the nucleotides at the -10 region of its cognate promoters, we tested whether base pair substitutions in the -10 region of a sigma B-dependent promoter could signal its...
