Structure Motif Annotation: Mechanism and Catalytic Site Atlas M-CSA Database Homepage Chains Enzyme Name Description Catalytic Residues dimethylglycine oxidase (tetrahydrofolate utilising)
M-CSA #879 Catalyses the oxidative demethylation of N,N-dimethylglycine to yield sarcosine, 5,10-methylenetetrahydrofolate and hydrogen peroxide. The oxidation of dimethylglycine is coupled to the synthesis of 5,10-methylenetetrahydrofolate through an unusual substrate channelling mechanism. This channelling occurs by non-biased diffusion of the iminium intermediate through a large solvent cavity connecting active site 1 (N-terminus) and active site 2 (C-terminus). The synthesis of 5,10-methylenetetrahydrofolate (at active site 2) prevents the accumulation of formaldehyde (not shown), formed by hydrolysis of the iminium intermediate product (at active site 1).
Extent of motif is too large to support Structure Motif searching.
