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.

摘要

我们利用mini-Tn1O诱变来鉴定σD活性的负调控因子。九个独立插入位点被定位到五个基因：flgM、flgK、fliD、fliS和fliT，这表明枯草芽孢杆菌和鼠伤寒沙门氏菌中FlgM的输出调控方式相似。我们发现，flgM的缺失可使枯草芽孢杆菌的sinR缺失突变体恢复σD活性，尽管fla/che操纵子的表达不受SinR和FlgM的影响。
