Protein

Bacterioferritin

Gene

bfr

Organism
Nitrobacter winogradskyi (Nitrobacter agilis)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

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
May act as one of the electron carriers in the reverse electron-transport system from cytochrome c-552 to NADP+.

Catalytic activityi

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

Cofactori

Binds 1 heme B (iron-protoporphyrin IX) group per dimer.By similarity
Binds 2 iron ions per subunit. The catalytic dinuclear iron-binding site within each subunit is known as the ferroxidase center By similarity.By similarity
