Spo0A mutants of Bacillus subtilis with sigma factor-specific defects in transcription activation.

Journal of bacteriology - 1 Jul 1998

Hatt J K, Youngman P

Abstract excerpt

The transcription factor Spo0A of Bacillus subtilis has the unique ability to activate transcription from promoters that require different forms of RNA polymerase holoenzyme. One class of Spo0A-activated promoter, which includes spoIIEp, is recognized by RNA polymerase associated with the primary sigma factor, sigma A (sigmaA); the second, which includes spoIIAp, is recognized by RNA polymerase associated with an...
