4Fe-4S dicluster domain-containing protein
This family includes proteins containing domains which bind to iron-sulfur clusters. Members include bacterial ferredoxins, various dehydrogenases, and various reductases. The structure of the domain is an alpha-antiparallel beta sandwich. (from Pfam)

FixG Ig-like domain-containing protein
This domain is part of a transmembrane protein, FixG, itself part of the FixGHIS operon closely associated with the FixNOPQ operon that is the symbiotically essential cbb3-type haem-copper oxidase complex. FixG expression is induced by oxygen-deprivation. This C-terminal domain adopts an E-set Ig-like fold. [1]. 8661920.

cytochrome c oxidase accessory protein CcoG
cytochrome c oxidase accessory protein CcoG is a RdxA/RdxB/FixG family protein similar to Sinorhizobium meliloti nitrogen fixation protein FixG and Rhodobacter sphaeroides RdxB and is required for the formation of a high-affinity cbb3-type cytochrome oxidase
Member of this ferredoxin-like protein family are found exclusively in species with an operon encoding the cbb3 type of cytochrome c oxidase (cco-cbb3), and near the cco-cbb3 operon in about half the cases. The cco-cbb3 is found in a variety of proteobacteria and almost nowhere else, and is associated with oxygen use under microaerobic conditions. Some (but not all) of these proteobacteria are also nitrogen-fixing, hence the gene symbol fixG. FixG was shown essential for functional cco-cbb3 expression in Bradyrhizobium japonicum.
