This entry represents the N-terminal domain of a group of enzymes that utilise NADP or NAD, known as the GFO/IDH/MOCA family, which includes enzymes that catalyse different chemical reactions such as oxidation and reduction of carbohydrates, oxidation of trans-dihydrodiols, reduction of biliverdin and hydrolysation of glycosidic bonds. This domain adopts a a typical Rossmann fold.	Domain
