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

ATP + 2-dehydro-3-deoxy-D-gluconate

\rightleftharpoons

ADP + 6-phospho-2-dehydro-3-deoxy-D-gluconate

Thus, the two substrates of this enzyme are ATP and 2-dehydro-3-deoxy-D-gluconate, whereas its two products are ADP and 6-phospho-2-dehydro-3-deoxy-D-gluconate.[1]

This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:2-dehydro-3-deoxy-D-gluconate 6-phosphotransferase. Other names in common use include 2-keto-3-deoxygluconokinase, 2-keto-3-deoxy-D-gluconic acid kinase, 2-keto-3-deoxygluconokinase (phosphorylating), 2-keto-3-deoxygluconate kinase, and ketodeoxygluconokinase. This enzyme participates in pentose phosphate pathway and pentose and glucuronate interconversions.
