RA   Park S.G., Yudkin M.D.;
RT   "Sequencing and phylogenetic analysis of the spoIIA operon from diverse
RT   Bacillus and Paenibacillus species.";
RL   Gene 194:25-33(1997).
CC   -!- FUNCTION: In the phosphorylated form it could act as an anti-anti-sigma
CC       factor that counteracts SpoIIAB and thus releases sigma f from
CC       inhibition. {ECO:0000250}.
CC   -!- PTM: Phosphorylated by SpoIIAB on a serine residue. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the anti-sigma-factor antagonist family.
CC       {ECO:0000305}.
