Anti-sigma F factor antagonist

Gene

spoIIAA

Organism
Lysinibacillus sphaericus (Bacillus sphaericus)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

In the phosphorylated form it could act as an anti-anti-sigma factor that counteracts SpoIIAB and thus releases sigma f from inhibition.By similarity
