The katX gene of Bacillus subtilis is under dual control of sigmaB and sigmaF.

Molecular & general genetics : MGG - 1 Aug 1999

Abstract excerpt

The gene katX, which encodes a catalase in Bacillus subtilis, is transcribed by EsigmaF in the pre-spore. This catalase is responsible for the resistance to hydrogen peroxide shown by germinating and outgrowing spores. We demonstrated that katX is also a sigmaB-dependent general stress gene, since it is strongly induced by heat, salt and ethanol stress, as well as by energy depletion. The -10 and -35 sequences of...
