RT   bacterioferritin.";
RL   FEBS Lett. 390:261-264(1996).
CC   -!- FUNCTION: May perform analogous functions in iron detoxification and
CC       storage to that of animal ferritins (By similarity). Contains
CC       approximately 750 iron atoms per molecule. {ECO:0000250,
CC       ECO:0000269|PubMed:8706873}.
CC   -!- SUBUNIT: Oligomer consisting of two types of subunits: light chain and
CC       heavy chain. {ECO:0000269|PubMed:8706873}.
CC   -!- SIMILARITY: Belongs to the bacterioferritin family. {ECO:0000255}.
