Spore photoproduct lyase operon (splAB) regulation during Bacillus subtilis sporulation: modulation of splB-lacZ fusion expression by P1 promoter mutations and by an in-frame deletion of splA.

Abstract excerpt

EsigmaG-dependent transcription of the splAB operon in the forespore at stage III of Bacillus subtilis sporulation initiates from two promoters, P1 preceding splA (major) and P3 preceding splB (minor). To explore the possible role of splA in controlling splB-encoded spore photoproduct lyase expression, we measured beta-galactosidase from splB-lacZ fusions integrated at the SPbeta prophage locus which contained...
