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:0000269|PubMed:8358793}.
CC -!- PTM: Phosphorylated by SpoIIAB on a serine residue.
CC {ECO:0000269|PubMed:7751305}.
CC -!- SIMILARITY: Belongs to the anti-sigma-factor antagonist family.
CC {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=AAA22789.1; Type=Erroneous initiation; Evidence={ECO:0000305};
