EC 1.5.8.3 Details

show Brenda entry

EC number

1.5.8.3

Accepted name

sarcosine dehydrogenase

Reaction

sarcosine + 5,6,7,8-tetrahydrofolate + electron-transfer flavoprotein = glycine + 5,10-methylenetetrahydrofolate + reduced electron-transfer flavoprotein

Other name(s)

sarcosine N-demethylase, monomethylglycine dehydrogenase, sarcosine:(acceptor) oxidoreductase (demethylating), sarcosine:electron-transfer flavoprotein oxidoreductase (demethylating)

Systematic name

sarcosine, 5,6,7,8-tetrahydrofolate:electron-transferflavoprotein oxidoreductase (demethylating,5,10-methylenetetrahydrofolate-forming)

CAS registry number

37228-65-2, 93389-49-2

Comment

A flavoprotein (FMN) found in eukaryotes. In the absence of tetrahydrofolate the enzyme produces formaldehyde. cf. EC 1.5.3.1, sarcosine oxidase (formaldehyde-forming), and EC 1.5.3.24, sarcosine oxidase (5,10-methylenetetrahydrofolate-forming).

History

created 1972 as EC 1.5.99.1, transferred 2012 to EC 1.5.8.3, modified 2022
