General annotation (Comments)
| Function | 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. Ref.4 Ref.5 |
| Catalytic activity | ATP + a protein = ADP + a phosphoprotein. HAMAP-Rule MF_00637 |
| Developmental stage | Interaction with SpoIIAB inhibits sigma F activity throughout the cell before the formation of the asymmetric septum; after septation the interaction is confined to the mother cell, and sigma F activity is released in the prespore. HAMAP-Rule MF_00637 |
| Sequence similarities | Belongs to the anti-sigma-factor family. |
