Reaction: (S)-2-hydroxyglutarate + a quinone = 2-oxoglutarate + a quinol
Other name(s): L-2-hydroxyglutarate dehydrogenase; lhgO (gene name); ygaF (gene name)
Systematic name: (S)-2-hydroxyglutarate:quinone oxidoreductase
Comments: The enzyme, characterized from the bacterium Escherichia coli, contains an FAD cofactor that is not covalently attached. It is bound to the cytoplasmic membrane and is coupled to the membrane quinone pool.
