Anti-sigma F factor

Gene

spoIIAB

Organism
Clostridium perfringens (strain ATCC 13124 / DSM 756 / JCM 1290 / NCIMB 6125 / NCTC 8237 / Type A)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

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.UniRule annotation

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.UniRule annotation
