Glyceraldehyde-3-phosphate dehydrogenase (NAD(P)+)
Script error: No such module "Unsubst". Template:Infobox enzyme In enzymology, a glyceraldehyde-3-phosphate dehydrogenase (NAD(P)+) (EC 1.2.1.59) is an enzyme that catalyzes the chemical reaction
- D-glyceraldehyde 3-phosphate + phosphate + NAD(P)+ 3-phospho-D-glyceroyl phosphate + NAD(P)H + H+
The four substrates of this enzyme are D-glyceraldehyde 3-phosphate, phosphate, NAD+, and NADP+, whereas its four products are 3-phospho-D-glyceroyl phosphate, NADH, NADPH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of a donor with NAD+ or NADP+ as an acceptor. The systematic name of this enzyme class is D-glyceraldehyde 3-phosphate:NAD(P)+ oxidoreductase (phosphorylating). Other names in common use include triosephosphate dehydrogenase (NAD(P)) (phosphorylating), and glyceraldehyde-3-phosphate dehydrogenase (NAD(P)) (phosphorylating).
Structural studies
As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code 2CZC.
