This enzyme belongs to the family of lyases, specifically the oxo-acid-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is 4-hydroxy-2-oxoglutarate glyoxylate-lyase (pyruvate-forming). Other names in common use include 2-oxo-4-hydroxyglutarate aldolase, hydroxyketoglutaric aldolase, 4-hydroxy-2-ketoglutaric aldolase, 2-keto-4-hydroxyglutaric aldolase, 4-hydroxy-2-ketoglutarate aldolase, 2-keto-4-hydroxyglutarate aldolase, 2-oxo-4-hydroxyglutaric aldolase, DL-4-hydroxy-2-ketoglutarate aldolase, hydroxyketoglutarate aldolase, 2-keto-4-hydroxybutyrate aldolase, and 4-hydroxy-2-oxoglutarate glyoxylate-lyase. This enzyme participates in arginine and proline metabolism and glyoxylate and dicarboxylate metabolism.
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 1WAU and 2C0A.
