BRITE hierarchy
Sysname
N,N-dimethylglycine,5,6,7,8-tetrahydrofolate:oxygen oxidoreductase (demethylating,5,10-methylenetetrahydrofolate-forming)
Reaction(IUBMB)
N,N-dimethylglycine + 5,6,7,8-tetrahydrofolate + O2 = sarcosine + 5,10-methylenetetrahydrofolate + H2O2 [RN:
R01564 ]
Reaction(KEGG)
Substrate
Product
Comment
A flavoprotein (FAD). The enzyme, characterized from the bacterium Arthrobacter globiformis, contains two active sites connected by a large "reaction chamber". An imine intermediate is transferred between the sites, eliminating the production of toxic formaldehyde. In the absence of folate the enzyme does form formaldehyde. Does not oxidize sarcosine. cf. EC
1.5.8.4 , dimethylglycine dehydrogenase.
History
