RL Submitted (DEC-2002) to the EMBL/GenBank/DDBJ databases.
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-
CC [protein]; Xref=Rhea:RHEA:17989, Rhea:RHEA-COMP:9863, Rhea:RHEA-
