  • Title: Expression of Escherichia coli DcuS-R two-component regulatory system is regulated by the secondary internal promoter which is activated by CRP-cAMP.

    Journal: J Microbiol; 2007 Jun; 45(3):234-40. PubMed ID: 17618229.
    Abstract:
    The DcuS-R two-component system of Escherichia coli senses C4-dicarboxylates of the medium and regulates expression of the genes related to utilization of them. It is known that phospho-DcuR induces expression of genes such as the dcuB-fumB operon, the frdABCD operon, and the dctA gene. We analyzed promoters of the dcuS-R operon to elucidate the transcriptional regulation system. We found a novel internal promoter within the dcuS gene that is regulated by the transcriptional regulator, CRP-cAMP, in both aerobic and anaerobic conditions.
