    The protein

    Protein family

  • [SW|Fur family]

    • Paralogous protein(s)

  • [protein|00BCAAE16576DC5426A652580C69A570FC7A1C2C|PerR], [protein|F899F1EE27E6D503BCC06BC52E3C7FD80B8EF725|Fur]

    • 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 [SW|Zur regulon] [Pubmed|21821657]
  • zinc binding is negatively co-operative resulting in step-wise induction of the genes of the [SW|Zur regulon] upon zinc depletion [Pubmed|27561249]
