1.5.3.1

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 1.5.3.24, sarcosine oxidase (5,10-methylenetetrahydrofolate-forming).
