CC   -!- COFACTOR:
CC       Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC         Evidence={ECO:0000250|UniProtKB:P94692};
CC       Note=Binds 2 [4Fe-4S] clusters. {ECO:0000250|UniProtKB:P94692};
CC   -!- SUBUNIT: Heterotetramer of one alpha, one beta, one delta and one gamma
CC       chain.
CC   -!- CAUTION: There seems to be a sequencing error that fuses together porC
CC       and porD. We have cut the ORF into its two constituents. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAB86210.1; Type=Erroneous initiation; Evidence={ECO:0000305};
