Expression and regulation
- Operon:
- Regulation:
- 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
