    The protein

    Protein family

  • Fe/B12 periplasmic-binding domain (according to Swiss-Prot)
  • [SW|Domains]

  • Two independent non-symmetric globular domains, connected by a long alpha-helix (residues 143-164 of the mature protein).
  • Modification

  • FeuA is a lipoprotein with a N-acetyl-S-diacyl-glyceryl-cysteine structure [Pubmed|22303020]
  • Structure

  • [PDB|2PHZ], [PDB|2WI8], [PDB|2WHY] (complex with ferri-bacillibactin), [PDB|2XUZ] (complex with ferri-enterobactin), [PDB|2XV1] (complex with ferric mecam)
  • [SW|Localization]

  • associated to the membrane (lipoprotein) [Pubmed|22303020]
  • extracellular (signal peptide) [Pubmed|18957862]

  • regulation

  • expression during spore [SW|germination] is strongly reduced under conditions of osmotic stress [Pubmed|27766092]
  • induced by iron starvation (second wave to allow iron scavenging from the environment) ([protein|F899F1EE27E6D503BCC06BC52E3C7FD80B8EF725|Fur]) [pubmed|29133393]
  • expression of the operon is strongly induced at the beginning of [SW|biofilm formation] [pubmed|31113899]
  • additional information

  • the presence of an iron-responsive element bound by [SW|CitB] between ''[SW|feuA]'' and ''[SW|feuB]'' suggests iron-dependent regulation by [SW|CitB] [Pubmed|10468622]
