In enzymology, a dimethylglycine oxidase () is an enzyme that catalyzes the chemical reaction N,N-dimethylglycine + H2O + O2 sarcosine + formaldehyde + H2O2 The 3 substrates of this enzyme are N,N-dimethylglycine, H2O, and O2, whereas its 3 products are sarcosine, formaldehyde, and H2O2. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with oxygen as acceptor. The systematic name of this enzyme class is N,N-dimethylglycine:oxygen oxidoreductase (demethylating). It employs one cofactor, FAD. Structural studies As of late 2007, 3 structures have been solved for this class of enzymes, with PDB accession codes , , and . References EC 1.5.3 Flavoproteins Enzymes of known structure
