UniProtKB description: Functions as an intracellular molybdate sensor. The ModE-Mo complex acts as a repressor of the modABC operon, which is involved in the transport of molybdate (PubMed:8550508). Binds modA promoter DNA in the absence of molybdate, however molybdate binding confers increased DNA affinity (PubMed:9044285, PubMed:9210473). Binds the promoter of moaA activating its transcription; binding is not enhanced by molybdate (PubMed:9044285). The protein dimer binds the consensus palindrome sequence 5'-TATAT-N7-TAYAT-3' and a variant 5'-TGTGT-N7-TGYGT-3' (PubMed:16205910, PubMed:9044285, PubMed:9210473). Acts as a regulator of the expression of 67 genes, many of which encode molybdoenzymes, acts both directly and indirectly (PubMed:10206709, PubMed:16205910, PubMed:9466267). ModE also binds tungstate (PubMed:11259434, PubMed:9210473).
