A region in the Bacillus subtilis transcription factor Spo0A that is important for spoIIG promoter activation.

Journal of bacteriology - 1 Jul 1998

Buckner C M, Schyns G, Moran C P

Abstract excerpt

Spo0A is a DNA binding protein in Bacillus subtilis required for the activation of spoIIG and other promoters at the onset of endospore formation. Activation of some of these promoters may involve interaction of Spo0A and the sigmaA subunit of RNA polymerase. Previous studies identified two single-amino-acid substitutions in sigmaA, K356E and H359R, that specifically impaired Spo0A-dependent transcription in...
