Identification
Name:Catecholate siderophore receptor fiu
Synonyms:
  • Ferric iron uptake protein
  • TonB-dependent receptor fiu
Gene Name:fiu
Enzyme Class:Not Available
Biological Properties
General Function:Involved in receptor activity
Specific Function:Involved in the active transport across the outer membrane of iron complexed with catecholate siderophores such as dihydroxybenzoylserine and dihydroxybenzoate. It derives its energy for transport by interacting with the trans-periplasmic membrane protein tonB. Can also transport catechol-substitued cephalosporins. Receptor for microcins M, H47 and E492
Cellular Location:Cell outer membrane
