The activation of sigma(G), a transcription factor, in Bacillus subtilis is coupled to the completion of engulfment during sporulation. SpoIIAB, an anti-sigma factor involved in regulation of sigma(F), is also shown to form a complex with sigma(G) in vitro. SpoIIAA, the corresponding anti-anti-sigma factor, can disrupt the SpoIIAB:sigma(G) complex, releasing free sigma(G). The data suggest the existence of an as-yet-unknown mechanism to keep sigma(G) inactive prior to engulfment.
