IUBMB Enzyme Nomenclature


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: The enzyme, which has been characterized from the plant Arabidopsis thaliana, is highly specific for (R)-2-hydroxyglutarate. It has low activity with (R)-lactate, (R)-2-hydroxybutyrate and meso-tartrate, and no activity with the (S) isomers.
