SYSTEMATIC NAME
IUBMB Comments
N,N-dimethylglycine,5,6,7,8-tetrahydrofolate:electron-transferflavoprotein oxidoreductase (demethylating,5,10-methylenetetrahydrofolate-forming)
A flavoprotein, containing a histidyl(Npi)-(8alpha)FAD linkage at position 91 in the human protein. An imine intermediate is channeled from the FAD binding site to the 5,6,7,8-tetrahydrofolate binding site through a 40 A tunnel [5,8,9]. In the absence of 5,6,7,8-tetrahydrofolate the enzyme forms formaldehyde [5,9].
