- Research Article | SpotlightContact with the CsrA Core Is Required for Allosteric Inhibition by FliW in Bacillus subtilis
CsrA is a small dimeric protein that binds RNA and is one of the few known examples of transcript-specific protein regulators of translation in bacteria. A protein called FliW binds to and antagonizes CsrA to govern flagellin homeostasis and flagellar assembly. Despite having a high-resolution three-dimensional structure of the FliW-CsrA complex, the mechanism of noncompetitive inhibition remains unresolved. Here, we identify FliW...

Regulation of metabolism and virulence in C. burnetii is not well understood. Here, we show that C. burnetii small RNA 12 (CbsR12) is highly transcribed in the metabolically active large-cell variant compared to the nonreplicative small-cell variant. We show that CbsR12 directly regulates several...
