General annotation (Comments)

Function

Terminal reductase during anaerobic growth on various sulfoxide and N-oxide compounds.

Catalytic activity

Trimethylamine + 2 (ferricytochrome c)-subunit + H2O = trimethylamine N-oxide + 2 (ferrocytochrome c)-subunit + 2 H+.

Cofactor

Binds 1 molybdenum ion per subunit.

Binds 2 molybdopterin guanine dinucleotide (MGD) groups per subunit.

Subunit structure

Monomer By similarity.

Subcellular location

Periplasm.

Post-translational modification

Predicted to be exported by the Tat system. The position of the signal peptide cleavage has been experimentally proven.

Sequence similarities

Belongs to the prokaryotic molybdopterin-containing oxidoreductase family.
