2.7.8.43 additional information expression of EptA (PmrC) is under the control of PmrA/PmrB -, 723212 2.7.8.43 additional information no upregulation of pmrA by Fe3+ and Mg2+ in strain ATCC 19606 733107 2.7.8.43 additional information PetL expression is positively regulated by the global regulator Fis and negatively regulated by an Hfq-dependent small RNA -, 761244 2.7.8.43 additional information transcription of the enzyme eptAPa is regulated by zinc via the ColRS two-component system. The two-component system response regulator ColR activates eptAPa transcription. Transcription of eptAPa is induced by 2 mM ZnSO4 approximately 21fold 739106 2.7.8.43 up the peptA (eptA promoter) is induced sevenfold in the presence of Fe3+, induction is lost in enzyme mutant strain CH020 (DELTApmrA) 723212
