FlgM is a primary regulator of sigmaD activity, and its absence restores motility to a sinR mutant.

Abstract

We have used mini-Tn1O mutagenesis to identify negative regulators of sigmaD activity. Nine independent insertions were mapped to five genes: flgM, flgK, fliD, fliS, and fliT, suggesting that FlgM export is regulated similarly in Bacillus subtilis and Salmonella typhimurium. We show that a deletion of flgM can restore sigmaD activity to a sinR null mutant of B. subtilis, although fla/che operon expression is affected by neither SinR nor FlgM.
