EC 4.1.3.42     
Accepted name: (4S)-4-hydroxy-2-oxoglutarate aldolase
Reaction: (4S)-4-hydroxy-2-oxoglutarate = pyruvate + glyoxylate
Glossary: (4S)-4-hydroxy-2-oxoglutatrate = (S)-2-hydroxy-4-oxopentanedioate = L-4-hydroxy-2-oxoglutarate
Other name(s): 2-oxo-4-hydroxyglutarate aldolase (ambiguous); hydroxyketoglutaric aldolase (ambiguous); 4-hydroxy-2-ketoglutaric aldolase (ambiguous); 2-keto-4-hydroxyglutaric aldolase (ambiguous); 4-hydroxy-2-ketoglutarate aldolase (ambiguous); 2-keto-4-hydroxyglutarate aldolase (ambiguous); 2-oxo-4-hydroxyglutaric aldolase (ambiguous); hydroxyketoglutarate aldolase (ambiguous); 2-keto-4-hydroxybutyrate aldolase (ambiguous); 4-hydroxy-2-oxoglutarate glyoxylate-lyase (ambiguous); eda (gene name)
Systematic name: (4S)-4-hydroxy-2-oxoglutarate glyoxylate-lyase (pyruvate-forming)
Comments: The enzyme from the bacterium Escherichia coli is specific for the (S) enantiomer. That enzyme is trifunctional, and also catalyses the reactions of EC 4.1.1.3, oxaloacetate decarboxylase and EC 4.1.2.14, 2-dehydro-3-deoxy-phosphogluconate aldolase. cf. EC 4.1.3.16, 4-hydroxy-2-oxoglutarate aldolase.
