Sarcosine oxidase

Sarcosine oxidase (SOX) catalyzes the demethylation of sarcosine+O2+H4-tetrahydrofolate to produce glycine, hydrogen peroxide and 5, 10-methylene-tetrahydrofolate. Sarcosine metabolism can be the source of carbon and energy for many microorganisms. SOXs are found as monomers, heterodirmers and heterotetramers. Monomeric SOX uses FAD as cofactor. Heterotetrameric SOX uses FAD and FMN as cofactors.
