Immunofluorescence microscopy was used to study the establishment
of compartment-specific transcription during sporulation in
Bacillus subtilis. Analysis of the distribution of the
anti-anti-sigma factor, SpoIIAA, in a variety of mutant backgrounds
supports a model in which the SpoIIE phosphatase, which activates
SpoIIAA by dephosphorylation, is sequestered onto the prespore face of the asymmetric septum. Thus, prespore-specific gene expression apparently arises as a result of the compartmentalization of SpoIIE protein. The results also suggest the existence of at least two compartment-specific programs of proteolysis, one dependent on the
mother cell-specific sigma factor
