Abstract

The Bacillus subtilis spoVD gene encodes a penicillin-binding protein required for spore morphogenesis. SpoIIID is a sequence-specific DNA-binding protein that activates or represses the transcription of many different genes. We have defined the spoVD promoter region and demonstrated that it is recognized by sigmaE RNA polymerase in vitro and that SpoIIID represses spoVD transcription. Two strong SpoIIID-binding sites were mapped in the spoVD promoter region, one overlapping the -35 region and the other encompassing the -10 region and the transcriptional start site.
