The two substrates of this enzyme are S-(hydroxymethyl)glutathione and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are S-formylglutathione, reduced NADH, and a proton. The enzyme can also use the alternative cofactor, nicotinamide adenine dinucleotide phosphate.[1][2][3][4][5]
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is S-(hydroxymethyl)glutathione:NAD+ oxidoreductase. Other names in common use include NAD-linked formaldehyde dehydrogenase (incorrect), formaldehyde dehydrogenase (incorrect), formic dehydrogenase (incorrect), class III alcohol dehydrogenase, ADH3, &chi, -ADH, FDH (incorrect), formaldehyde dehydrogenase (glutathione) (incorrect), GS-FDH (incorrect), glutathione-dependent formaldehyde dehydrogenase (incorrect), NAD-dependent formaldehyde dehydrogenase, GD-FALDH, and NAD- and glutathione-dependent formaldehyde dehydrogenase. This enzyme participates in methane metabolism.
Structural studies
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 2FZE and 2FZW.
