[ | [https://www.uniprot.org/uniprot/SP2AB_GEOSE SP2AB_GEOSE] Binds to sigma F and blocks its ability to form an RNA polymerase holoenzyme (E-sigma F). Phosphorylates SpoIIAA on a serine residue. This phosphorylation may enable SpoIIAA to act as an anti-anti-sigma factor that counteracts SpoIIAB and thus releases sigma F from inhibition.[HAMAP-Rule:MF_00637] | ||
