Anti-sigma-F factor

An anti-sigma factor for sporulation specific sigma-F factor, by antagonizing sigma-F it allows the switch to sigma-G factor and progression to the late sporulation development stages .

Below are the list of possible Anti-sigma-F factor products. If you cannot find the target and/or product is not available in our catalog, please click here to contact us and request the product or submit your request for custom elisa kit production, custom recombinant protein production or custom antibody production. Custom ELISA Kits, Recombinant Proteins and Antibodies can be designed, manufactured and produced according to the researcher's specifications.

Anti-sigma F factor

Also known as Anti-sigma F factor (Stage II sporulation protein AB).
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.

Anti-sigma-F factor Fin

Also known as Anti-sigma-F factor Fin (Suppressor of recU and recB SubA).
An anti-sigma factor for sporulation specific sigma-F factor, by antagonizing sigma-F it allows the switch to sigma-G factor and progression to the late sporulation development stages (PubMed:21037003). Might stabilize or process Holliday junction intermediates, although this may be due to polar effects on the downstream mfd gene (PubMed:15317759).

Anti-sigma-F factor RsbW

Also known as Anti-sigma-F factor RsbW (Anti-sigma-F factor UsfX) (Regulator of SigF) (Sigma-F anti-sigma factor RsbW).
A cognate anti-sigma factor for alternative sigma factor SigF. Alternative sigma factors are held in an inactive form by an anti-sigma factor. Binds ATP and GTP, may hydrolyze both ().
