功能: catalytic activity:5,10-methenyltetrahydrofolate + H(2)O = 10-formyltetrahydrofolate.,catalytic activity:5,10-methylenetetrahydrofolate + NAD(+) = 5,10-methenyltetrahydrofolate + NADH.,cofactor:Magnesium.,developmental stage:Expressed only in developing normal tissues.,miscellaneous:This NAD-dependent bifunctional enzyme has very different kinetic properties than the larger NADP-dependent trifunctional enzyme and is unique in that it requires formation of an enzyme-magnesium complex to allow binding of NAD.,similarity:Belongs to the tetrahydrofolate dehydrogenase/cyclohydrolase family.,subunit:Homodimer.,
