The 4 substrates of this enzyme are D-glyceraldehyde 3-phosphate, phosphate, NAD+, and NADP+, whereas its 4 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 donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is D-glyceraldehyde 3-phosphate:NAD(P)+ oxidoreductase (phosphorylating). Other names in common use include (phosphorylating), triosephosphate dehydrogenase (NAD(P)), 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.
