Glycerol-3-phosphate dehydrogenase (NAD(P)+)

Enzyme group From Wikipedia, the free encyclopedia

In enzymology, glycerol-3-phosphate dehydrogenase [NAD(P)+] (EC 1.1.1.94) is an enzyme that catalyzes the chemical reaction

The two substrates of this enzyme are L-α-glycerophosphoric acid, and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are dihydroxyacetonephosphoric acid, 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 sn-glycerol-3-phosphate:NAD(P)+ 2-oxidoreductase. Other names in common use include L-glycerol-3-phosphate:NAD(P)+ oxidoreductase, glycerol phosphate dehydrogenase (nicotinamide adenine dinucleotide, (phosphate)), glycerol 3-phosphate dehydrogenase (NADP+), and glycerol-3-phosphate dehydrogenase [NAD(P)+]. This enzyme participates in glycerophospholipid metabolism.

Structural studies

As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code PDB: 1TXG.
