Function

[SP2SA_BACSU] Toxic component of a toxin-antitoxin (TA) module. Its toxic activity is neutralized by cognate antitoxin SpoIISB. Expression in the absence of SpoIISB permits sporulation to stage II, when plasmolysis zones and holes in the peptidoglycan layer are observed, resulting in cell death. Lethal when synthesized during vegetative growth in the absence of SpoIISB. In E.coli both the membrane bound and soluble domain are required in cis for toxin activity.[1] [SP2SB_BACSU] Antitoxin component of a toxin-antitoxin (TA) module. Antitoxin that binds cognate toxin SpoIISA and neutralizes its toxic activity; unlike most antitoxins it does not seem to be highly labile upon expression in E.coli.[2]

About this Structure
