Expression and regulation

• Operon:
  • spoIIIAA-spoIIIAB-spoIIIAC-spoIIIAD-spoIIIAE-spoIIIAF-spoIIIAG-spoIIIAH PubMed
  • spoIIIAG-spoIIIAH PubMed

• Sigma factor:
  • both promoters: SigE PubMed

• Regulation:
  • both promoters: expressed during sporulation in the mother cell (SigE) PubMed, switched off by SpoIIID PubMed

• Regulatory mechanism: SpoIIID: transcription repression PubMed

• Additional information: the internal promoter is essential for sporulation, it is twice as active as the promoter in front of spoIIIAA, suggesting that SpoIIIAG and SpoIIIAH are required in larger amounts as compared to the other products of the operon PubMed
