CC   -!- FUNCTION: Negative regulator of sigma-B activity. Phosphorylates and
CC       inactivates its specific antagonist protein, RsbV. Upon phosphorylation
CC       of RsbV, RsbW is released and binds to sigma-B, thereby blocking its
CC       ability to form an RNA polymerase holoenzyme (E-sigma-B).
CC       {ECO:0000255|HAMAP-Rule:MF_00638}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-
