CC -!- FUNCTION: Probably acts as a heme chaperone, transferring heme to an
CC unknown acceptor. Binds one molecule of heme per monomer, possibly
CC covalently (By similarity). Binds 1 [4Fe-4S] cluster. The cluster is
CC coordinated with 3 cysteines and an exchangeable S-adenosyl-L-
CC methionine (By similarity). {ECO:0000250|UniProtKB:P32131,
CC ECO:0000250|UniProtKB:P52062}.
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU01266};
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q9CGF7}.
CC -!- MISCELLANEOUS: Might carry two S-adenosyl-L-methionine binding sites
CC with only one binding to the iron-sulfur cluster.
CC {ECO:0000250|UniProtKB:P32131}.
CC -!- SIMILARITY: Belongs to the anaerobic coproporphyrinogen-III oxidase
CC family. HemW subfamily. {ECO:0000305}.
