Structural highlights
Function
[SP2AA_BACSU] In the phosphorylated form it could act as an anti-anti-sigma factor that counteracts SpoIIAB and thus releases sigma f from inhibition.[1]

Publication Abstract from PubMed
The establishment of differential gene expression in sporulating Bacillus subtilis involves four protein components, one of which, SpoIIAA, undergoes phosphorylation and dephosphorylation. We have used NMR spectroscopy to determine the solution structure of the nonphosphorylated form of SpoIIAA. The structure shows a fold consisting of a four-stranded beta-sheet and four alpha-helices. Knowledge of the structure helps to account for the phenotype of several strains of B. subtilis that carry known spoIIAA mutations and should facilitate investigations of the conformational consequences of phosphorylation.
