A LIVER mitochondrial matrix flavoenzyme that catalyzes the oxidation of SARCOSINE to GLYCINE and FORMALDEHYDE. Mutation in the enzyme causes sarcosinemia, a rare autosomal metabolic defect characterized by elevated levels of SARCOSINE in BLOOD and URINE.

A FLAVOPROTEIN enzyme that catalyzes the oxidative demethylation of dimethylglycine to SARCOSINE and FORMALDEHYDE.

An amino acid intermediate in the metabolism of choline.

A FLAVOPROTEIN, this enzyme catalyzes the oxidation of SARCOSINE to GLYCINE; FORMALDEHYDE; and HYDROGEN PEROXIDE (H2O2).

Oxidoreductases, N-Demethylating are enzymes that catalyze the oxidation of N-methyl groups to carbonyl groups, typically found in xenobiotic metabolism, involving the removal of methyl groups from various substrates using molecular oxygen.
