Bacterioferritin

Gene

bfr

Organism
Streptomyces coelicolor (strain ATCC BAA-471 / A3(2) / M145)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Iron-storage protein, whose ferroxidase center binds Fe2+ ions, oxidizes them by dioxygen to Fe3+, and participates in the subsequent Fe3+ oxide mineral core formation within the central cavity of the protein complex.By similarity

Catalytic activityi

4 Fe2+ + 4 H+ + O2 = 4 Fe3+ + 2 H2O.

Cofactori

Protein has several cofactor binding sites:
  • heme bBy similarityNote: Binds 1 heme b (iron(II)-protoporphyrin IX) group per dimer.By similarity
  • Fe cationBy similarityNote: Binds 2 iron ions per subunit. The catalytic dinuclear iron-binding site within each subunit is known as the ferroxidase center.By similarity

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
