Reaction: sarcosine + H2O + electron-transfer flavoprotein = glycine + formaldehyde + reduced electron-transfer flavoprotein
Other name(s): sarcosine N-demethylase; monomethylglycine dehydrogenase; sarcosine:(acceptor) oxidoreductase (demethylating)
Systematic name: sarcosine:electron-transfer flavoprotein oxidoreductase (demethylating)
Comments: A flavoprotein (FMN). Tetrahydrofolate is also a substrate, being converted to N5,N10-methylenetetrahydrofolate.
