IUBMB Enzyme Nomenclature

EC 1.1.99.39

Accepted name: D-2-hydroxyglutarate dehydrogenase

Reaction: (R)-2-hydroxyglutarate + acceptor = 2-oxoglutarate + reduced acceptor

Other name(s): AtD-2HGDH

Systematic name: (R)-2-hydroxyglutarate:acceptor 2-oxidoreductase

Comments: Contains FAD. The enzyme has no activity with NAD+ or NADP+, and was assayed in vitro using artificial electron acceptors. It has lower activity with (R)-lactate, (R)-2-hydroxybutyrate and meso-tartrate, and no activity with the (S) isomers. The mammalian enzyme is stimulated by Zn2+, Co2+ and Mn2+.
