Regulation of sigma D expression and activity by spo0, abrB, and sin gene products in Bacillus subtilis.

RESUMO
Expression of sigma D protein and of the hag gene, which is transcribed by the sigma D holoenzyme, is not dependent on spo0, abrB, or sin gene products in Bacillus subtilis. Preliminary results, however, suggest that a signal mediated by the spo0K locus may be responsible for the inhibition of sigma D activity during the stationary phase.
