Protein family
[wiki|Fur family] (according to UniProt)
Structure
[PDB|2FE3] ([protein|00BCAAE16576DC5426A652580C69A570FC7A1C2C|perR], 35% identity) [pubmed|16925555]
[AF|P54479]
Modification
phosphorylated on ser/ thr/ tyr [Pubmed|16493705]
Effectors of protein activity
sequential binding of zinc (two atoms per monomer) results in the activation of Zur dimer and thus in repression of the genes of the [wiki|Zur regulon] [Pubmed|21821657]
zinc binding is negatively co-operative resulting in step-wise induction of the genes of the [wiki|Zur regulon] upon zinc depletion [Pubmed|27561249]
