EC Tree
1.2.99.8 glyceraldehyde dehydrogenase (FAD-containing)IUBMB Comments
The enzyme from the archaeon Sulfolobus acidocaldarius catalyses the oxidation of D-glyceraldehyde in the nonphosphorylative Entner-Doudoroff pathway. With 2,6-dichlorophenolindophenol as artificial electron acceptor, the enzyme shows a broad substrate range, but is most active with D-glyceraldehyde. It is not known which acceptor is utilized in vivo. The iron-sulfur protein contains FAD and molybdopterin guanine dinucleotide.
