CC -!- FUNCTION: Mediates electron transfer from NADH to oxygen, reducing it
CC to water. This modular protein has 3 redox cofactors, in other
CC organisms the same activity requires 2 or 3 proteins (By similarity).
CC {ECO:0000250}.
CC -!- COFACTOR:
CC Name=Fe cation; Xref=ChEBI:CHEBI:24875;
CC Note=Binds 2 iron ions per subunit.;
CC -!- MISCELLANEOUS: By homology with NorV in E.coli, may be involved in
CC nitric oxide detoxification. {ECO:0000250}.
CC -!- SIMILARITY: In the N-terminal section; belongs to the zinc metallo-
CC hydrolase group 3 family. {ECO:0000305}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the flavodoxin
CC reductase family. {ECO:0000305}.
