Gluconokinase - Misplaced Pages

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.
