Phosphorylation and RsbX-dependent dephosphorylation of RsbR in the RsbR-RsbS complex of Bacillus subtilis.

Abstract excerpt

In the pathway that controls sigmaB activity, the RsbR-RsbS complex plays an important role by trapping RsbT, a positive regulator of sigmaB of Bacillus subtilis. We have proposed that at the onset of stress, RsbR becomes phosphorylated, resulting in an enhanced activity of RsbT towards RsbS. RsbT is then free to interact with and activate RsbU, which in turn ultimately activates sigmaB. In this study with...
