In enzymology, a methylenetetrahydrofolate reductase (ferredoxin) (EC 1.5.7.1) is an enzyme that catalyzes the chemical reaction
- 5-methyltetrahydrofolate + 2 oxidized ferredoxin 5,10-methylenetetrahydrofolate + 2 reduced ferredoxin + 2 H+
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.
