CC   -!- FUNCTION: Reduces trimethylamine-N-oxide (TMAO) into trimethylamine; an
CC       anaerobic reaction coupled to energy-yielding reactions. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 Fe(III)-[cytochrome c] + H2O + trimethylamine = 2 Fe(II)-
CC         [cytochrome c] + 3 H(+) + trimethylamine N-oxide;
CC         Xref=Rhea:RHEA:24236, Rhea:RHEA-COMP:10350, Rhea:RHEA-COMP:14399,
CC         ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:15724,
CC         ChEBI:CHEBI:29033, ChEBI:CHEBI:29034, ChEBI:CHEBI:58389; EC=1.7.2.3;
CC   -!- COFACTOR:
CC       Name=Mo-bis(molybdopterin guanine dinucleotide);
CC         Xref=ChEBI:CHEBI:60539; Evidence={ECO:0000250};
CC       Note=Binds 1 molybdenum-bis(molybdopterin guanine dinucleotide) (Mo-
CC       bis-MGD) cofactor per subunit. {ECO:0000250};
CC   -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000250}.
CC   -!- PTM: Predicted to be exported by the Tat system. The position of the
CC       signal peptide cleavage has not been experimentally proven.
CC   -!- SIMILARITY: Belongs to the prokaryotic molybdopterin-containing
CC       oxidoreductase family. {ECO:0000305}.
