Diphtheria toxin repressor

Diphtheria toxin repressor (DtxR) is an iron-dependent repressor which is synthesized by the diphtheria bacterium when it is in iron-poor environment. The DtxR regulates the expression of high affinity iron uptake system. Structural highlights DtxR structure contains an which contains , dimerization and metal-binding residues. DtxR contains . . . A C-terminal domain folds into SH3-like conformation.
