| - | + | [https://www.uniprot.org/uniprot/DMGO_ARTGO DMGO_ARTGO] Catalyzes the oxidative demethylation of N,N-dimethylglycine to yield sarcosine, formaldehyde and hydrogen peroxide. The oxidation of dimethylglycine is coupled to the synthesis of 5,10-methylenetetrahydrofolate through an unusual substrate channeling mechanism. This channeling occurs by nonbiased 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, formed by hydrolysis of the iminium intermediate product (at active site 1). Does not oxidize sarcosine.<ref>PMID:11422368</ref> <ref>PMID:11926836</ref> <ref>PMID:12912903</ref> <ref>PMID:19369258</ref> | |
