IUBMB Enzyme Nomenclature

EC 1.5.8.3

Accepted name: sarcosine dehydrogenase

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.
