Abstract excerpt
The presence of a second SigH promoter in the sigA operon of Bacillus subtilis was demonstrated by use of a promoter probe plasmid, a sigH deletion mutant, primer extension studies, and in vitro transcription with E sigma H holoenzyme. Both SigH promoters were expressed at low levels even during the growth phase but were expressed at higher levels during the early stationary phase. Expression from the upstream...
