GO
GO:0008924 Catalysis of the reaction: (S)-malate + a quinone = oxaloacetate + a quinol. Vitamin K (menaquinone) and several other quinones can act as acceptors. GO:0006099 A nearly universal metabolic pathway in which the acetyl group of acetyl coenzyme A is effectively oxidized to two CO2 and four pairs of electrons are transferred to coenzymes. The acetyl group combines with oxaloacetate to form citrate, which undergoes successive transformations to isocitrate, 2-oxoglutarate, succinyl-CoA, succinate, fumarate, malate, and oxaloacetate again, thus completing the cycle. In eukaryotes the tricarboxylic acid is confined to the mitochondria. See also glyoxylate cycle. GO:0047545 Catalysis of the reaction: (S)-2-hydroxyglutarate + acceptor = 2-oxoglutarate + reduced acceptor.
