CC -!- FUNCTION: Cargo protein of a type 1 encapsulin nanocompartment. May
CC help nucleate Fe atoms in the interior of the encapsulin
CC nanocompartment (Probable). Present in about 36 copies/encapsulin
CC nanocompartment (PubMed:25024436). {ECO:0000269|PubMed:25024436,
CC ECO:0000305|PubMed:25024436}.
CC -!- SUBCELLULAR LOCATION: Encapsulin nanocompartment
CC {ECO:0000269|PubMed:25024436}. Note=Probably lies against the interior
CC face of the nanocompartment. {ECO:0000305|PubMed:25024436}.
CC -!- DISRUPTION PHENOTYPE: Forms wild-type fruiting bodies.
CC {ECO:0000269|PubMed:19996678}.
CC -!- BIOTECHNOLOGY: The encapsulin and a cargo construct (an encB-encC-encD
CC fusion) can be overexpressed in E.coli and in human HEK293T cells. In
CC HEK293T in the presence of 0.5 M ferrous ammonium sulfate
CC nanocompartments can be detected and used as cell markers. Coexpression
CC of this nanocompartment with a larger nanocompartment from
CC Q.thermotolerans (AC A0A0F5HPP7) allows of expression of different
CC sized iron-rich particles. The encapsulin shell proteins are not seen
CC to mix. {ECO:0000269|PubMed:31194509}.
CC -!- SIMILARITY: Belongs to the ferritin-like superfamily. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=ABF88760.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000269|PubMed:25024436};
