Identification
Name:Ferrienterobactin receptor
Synonyms:
  • Enterobactin outer-membrane receptor
Gene Name:fepA
Enzyme Class:Not Available
Biological Properties
General Function:Involved in receptor activity
Specific Function:This protein is involved in the initial step of iron uptake by binding ferrienterobactin (Fe-ENT), an iron chelatin siderophore that allows E.coli to extract iron from the environment. FepA also acts as a receptor for colicins B and D
Cellular Location:Cell outer membrane; Multi-pass membrane protein
SMPDB Pathways:
  • Biosynthesis of siderophore group nonribosomal peptides PW000760
KEGG Pathways:
  • Biosynthesis of siderophore group nonribosomal peptides ec01053
