Methylenetetrahydrofolate reductase (ferredoxin)
In enzymology, a methylenetetrahydrofolate reductase (ferredoxin) () is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are 5-methyltetrahydrofolate and oxidized ferredoxin, whereas its 3 products are 5,10-methylenetetrahydrofolate, reduced ferredoxin, and H. This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-NH group of donors with an iron-sulfur protein as acceptor. The systematic name of this enzyme class is 5-methyltetrahydrofolate:ferredoxin oxidoreductase. This enzyme is also called 5,10-methylenetetrahydrofolate reductase. This enzyme participates in one carbon pool by folate.
