rsbU : RsbV-specific serine-protein phosphatase [1]
Regulation of SigB is largely dependent on the availability of the anti-sigma factor RsbW. Under normal conditions, RsbW binds SigB and sequesters it in an inactive confirmation. Alternatively, RsbW can bind RsbV, releasing SigB. Thus, RsbV acts as an "anti-anti-sigma factor". RsbW has a second domain that acts as an RsbV-specific kinase. RsbW can't bind to phosphorylated RsbV, thus maintaining a default state of RsbW-SigB sequestration as long as sufficient ATP is around to keep RsbV phosphorylated. When ATP levels drop or when levels of the RsbV-specific phosphatase RsbU increase, RsbW-RsbV binding becomes favored and SigB-dependent transcription is activated.
