2-dehydro-3-deoxygluconokinase (EC 2.7.1.45) is an enzyme that catalyzes the chemical reaction
The enzyme characterised from Escherichia coli converts 2-dehydro-3-deoxy-D-gluconic acid to 2-dehydro-3-deoxy-6-phospho-D-gluconic acid by transferring a phosphate group from the cofactor, adenosine triphosphate (ATP), which is converted to adenosine diphosphate (ADP).[1]
This enzyme is a transferase, specifically one 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. It participates in the pentose phosphate pathway.[2]
Structural studies
As of late 2007, only one structure has been solved for this class of enzymes, with the PDB accession code PDB: 1WYE.[3]
