Accepted name: sarcosine oxidase (formaldehyde-forming)
Reaction: sarcosine + H2O + O2 = glycine + formaldehyde + H2O2
Other name(s): MSOX; monomeric sarcosine oxidase; sarcosine oxidase (ambiguous)
Systematic name: sarcosine:oxygen oxidoreductase (demethylating)
Comments: The enzyme, reported from bacteria and fungi, catalyses the oxidative demethylation of sarcosine. It contains a FAD cofactor bound to an L-cysteine residue. cf. EC, sarcosine oxidase (5,10-methylenetetrahydrofolate-forming).
