In enzymology, a formate dehydrogenase (NADP+) () is an enzyme that catalyzes the chemical reaction formate + NADP+ CO2 + NADPH Thus, the two substrates of this enzyme are formate and NADP+, whereas its two products are CO2 and NADPH. This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is formate:NADP+ oxidoreductase. Other names in common use include NADP+-dependent formate dehydrogenase, and formate dehydrogenase (NADP+). This enzyme participates in methane metabolism. It has 3 cofactors: iron, Tungsten, and Selenium. Structural studies As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code .
