Dimethylamine dehydrogenase () is an enzyme that catalyzes the chemical reaction
The three substrates of this enzyme are dimethylamine, water, and an electron-transferring flavoprotein. Its products are methylamine, formaldehyde, and the reduced flavoprotein.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with a flavin as acceptor. The systematic name of this enzyme class is dimethylamine:electron-transferring flavoprotein oxidoreductase. It uses one cofactor, flavin mononucleotide.
