Protein attributes

Sequence length	850 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Reduces trimethylamine-N-oxide (TMAO) into trimethylamine; an anaerobic reaction coupled to energy-yielding reactions By similarity.
Catalytic activity	Trimethylamine + 2 (ferricytochrome c)-subunit + H2O = trimethylamine N-oxide + 2 (ferrocytochrome c)-subunit + 2 H+.
Cofactor	Molybdenum (molybdopterin) By similarity.
Subcellular location	Periplasm By similarity.
Post-translational modification	Predicted to be exported by the Tat system. The position of the signal peptide cleavage has not been experimentally proven.
Sequence similarities	Belongs to the prokaryotic molybdopterin-containing oxidoreductase family.
