All the promoters on this page are ''B. subtilis'' promoters that are '''negatively regulated''' meaning that increased levels of at least one transcription factor (other than the sigma factor) will decrease the activity of these promoters.

==Repressible ''B. subtilis'' &sigma;<sup>A</sup> promoters==
This section lists promoters that are recognized by [[Help:Promoters/Prokaryotic RNAP#E. coli RNA polymerases|''B. subtilis'' &sigma;<sup>A</sup> RNAP]].  &sigma;<sup>A</sup> is the major ''B. subtilis'' sigma factor so there should be RNAP present to transcribe these promoters under most growth conditions (although maximally during exponential growth).<br>

==Repressible ''B. subtilis'' &sigma;<sup>B</sup> promoters==
This section lists promoters that are recognized by [[Help:Promoters/Prokaryotic RNAP#E. coli RNA polymerases|''B. subtilis'' &sigma;<sup>B</sup> RNAP]].  &sigma;<sup>B</sup> is the major stationary phase ''E. coli'' sigma factor.  Use these promoters when you want high promoter activity during stationary phase or during starvation.  <br>
