IUBMB Comments
A flavoprotein (FAD). The enzyme from yeast and mammals catalyses a physiologically irreversible reduction of 5,10-methylenetetrahydrofolate to 5-methyltetrahydrofolate using NADPH as the electron donor. It plays an important role in folate metabolism by regulating the distribution of one-carbon moieties between cellular methylation reactions and nucleic acid synthesis. The enzyme contains an N-terminal catalytic domain and a C-terminal allosteric regulatory domain that binds S-adenosyl-L-methionine, which acts as an inhibitor. cf. EC, methylenetetrahydrofolate reductase (NADH); EC, methylenetetrahydrofolate reductase [NAD(P)H]; and EC, methylenetetrahydrofolate reductase (ferredoxin).
