IUBMB Enzyme Nomenclature


Accepted name: 2-oxoglutarate reductase

Reaction: (R)-2-hydroxyglutarate + NAD+ = 2-oxoglutarate + NADH + H+

Other name(s): serA (gene name)

Systematic name: (R)-2-hydroxyglutarate,NAD+ 2-oxidireductase

Comments: The enzyme catalyses a reversible reaction. The enzyme from the bacterium Peptoniphilus asaccharolyticus is specific for (R)-2-hydroxyglutarate [1,2]. The SerA enzyme from the bacterium Escherichia coli can also accept (S)-2-hydroxyglutarate with a much higher Km, and also catalyses the activity of EC, phosphoglycerate dehydrogenase [3].
