Abstract excerpt

Pairs of the ECF sigma factor and its anti-sigma factor, SigW and RsiW, of Bacillus-related species that inhabit extreme environments were heterologously expressed in B. subtilis. All the RsiWs, membrane proteins, failed to fill their function of repressing cognate SigW activity, despite their close structural similarities. Particularly, uncontrolled expression of Oceanobacillus iheyensis OISigW due to abortive...
