2-dehydro-3-deoxy-phosphogluconate aldolase

In enzymology, a 2-dehydro-3-deoxy-phosphogluconate aldolase is an enzyme that catalyzes the chemical reaction


 * 2-dehydro-3-deoxy-D-gluconate 6-phosphate $$\rightleftharpoons$$ pyruvate + D-glyceraldehyde 3-phosphate

Hence, this enzyme has one substrate, 2-dehydro-3-deoxy-D-gluconate 6-phosphate, and two products, pyruvate and D-glyceraldehyde 3-phosphate.

This enzyme belongs to the family of lyases, specifically the aldehyde-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is 2-dehydro-3-deoxy-D-gluconate-6-phosphate D-glyceraldehyde-3-phosphate-lyase (pyruvate-forming). Other names in common use include phospho-2-keto-3-deoxygluconate aldolase, KDPG aldolase, phospho-2-keto-3-deoxygluconic aldolase, 2-keto-3-deoxy-6-phosphogluconic aldolase, 2-keto-3-deoxy-6-phosphogluconate aldolase, 6-phospho-2-keto-3-deoxygluconate aldolase, ODPG aldolase, 2-oxo-3-deoxy-6-phosphogluconate aldolase, 2-keto-3-deoxygluconate-6-P-aldolase, 2-keto-3-deoxygluconate-6-phosphate aldolase, 2-dehydro-3-deoxy-D-gluconate-6-phosphate, and D-glyceraldehyde-3-phosphate-lyase. This enzyme participates in 3 metabolic pathways: pentose phosphate pathway, pentose and glucuronate interconversions, and arginine and proline metabolism.
