CC   -!- FUNCTION: Sigma factors are initiation factors that promote the
CC       attachment of RNA polymerase to specific initiation sites and are then
CC       released. Sigma B is not essential for sporulation; rather it is
CC       required for maximal expression of ctc and csbA which are transcribed
CC       in the early stationary phase under conditions inimical to sporulation.
CC       May play a role in the ability of the bacterium to adapt to various
CC       stresses but is not essential for its survival under these conditions.
CC       Positively regulates expression of its own operon.
CC   -!- INDUCTION: By heat shock, salt stress, oxidative stress, glucose
CC       limitation, oxygen limitation and entry into stationary phase.
CC   -!- SIMILARITY: Belongs to the sigma-70 factor family. SigB subfamily.
CC       {ECO:0000305}.
