In enzymology, a gluconokinase (EC 2.7.1.12) is an enzyme that catalyzes the chemical reaction

ATP + D-gluconate ADP + 6-phospho-D-gluconate

Thus, the two substrates of this enzyme are ATP and D-gluconate, whereas its two products are ADP and 6-phospho-D-gluconate.

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:D-gluconate 6-phosphotransferase. Other names in common use include gluconokinase (phosphorylating), and gluconate kinase. This enzyme participates in pentose phosphate pathway.

Structural studies

As of late 2007, 6 structures have been solved for this class of enzymes, with PDB accession codes 1KNQ, 1KO1, 1KO4, 1KO5, 1KO8, and 1KOF.
