    • regulation

    • additional information

  • the internal promoter is essential for sporulation, it is twice as active as the promoter in front of [protein|search|spoIIIAA], suggesting that [protein|search|SpoIIIAG] and [protein|search|SpoIIIAH] are required in larger amounts as compared to the other products of the operon [http://www.ncbi.nlm.nih.gov/sites/entrez/17693505 PubMed]
