CC   -!- FUNCTION: Involved in the hydrocarbon hydroxylating system, which
CC       transfers electrons from NADH to rubredoxin reductase and then through
CC       rubredoxin to alkane 1 monooxygenase. {ECO:0000250}.
CC   -!- COFACTOR:
CC       Name=Fe(3+); Xref=ChEBI:CHEBI:29034;
CC         Evidence={ECO:0000250|UniProtKB:Q9HTK8};
CC       Note=Binds 1 Fe(3+) ions per subunit. {ECO:0000250|UniProtKB:Q9HTK8};
CC   -!- SIMILARITY: Belongs to the rubredoxin family. {ECO:0000305}.
