PF02742 | Iron dependent repressor, metal binding and dimerisation domain (Fe_dep_repr_C) | Iron dependent repressor, metal binding and dimerisation domain | This family includes the Diphtheria toxin repressor [1]. It acts as an iron-binding repressor of diphtheria toxin gene expression and may serve as a global regulator of gene expression. DTXR comprises an N-terminal DNA-binding domain, an interface do ... | Domain | |
