General stress transcription factor sigmaB of Bacillus subtilis is a stable protein.

Abstract

The sigmaB subunit of Bacillus subtilis RNA polymerase governs the expression of a large general stress regulon. The results of pulse-chase and immunoprecipitation experiments showed that sigmaB is stable both in the presence and in the absence of the RsbW anti-sigma factor, the principal regulator of sigmaB in response to environmental signals.
