Characterization of Specific Nucleotide Substitutions in DtxR-Specific Operators of Corynebacterium diphtheriae That Dramatically Affect DtxR Binding, Operator Function, and Promoter Strength
The diphtheria toxin repressor (DtxR) of Corynebacterium diphtheriae uses Fe(2+) as a corepressor. Holo-DtxR inhibits transcription from the iron-regulated promoters (IRPs) designated IRP1 through IRP5 as well as from the promoters for the tox and hmuO genes. DtxR binds to 19-bp operators with the c...
