CC -!- FUNCTION: Binds to sigma F and blocks its ability to form an RNA
CC polymerase holoenzyme (E-sigma F). Phosphorylates SpoIIAA on a serine
CC residue. This phosphorylation may enable SpoIIAA to act as an anti-
CC anti-sigma factor that counteracts SpoIIAB and thus releases sigma F
CC from inhibition. {ECO:0000255|HAMAP-Rule:MF_00637}.
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-

CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-threonyl-[protein] = ADP + H(+) + O-phospho-L-
CC threonyl-[protein]; Xref=Rhea:RHEA:46608, Rhea:RHEA-COMP:11060,

CC EC=2.7.11.1; Evidence={ECO:0000255|HAMAP-Rule:MF_00637};
CC -!- SIMILARITY: Belongs to the anti-sigma-factor family.
