5-dehydro-2-deoxygluconokinase () is an enzyme that catalyzes the following chemical reaction:
The enzyme characterised from Aerobacter aerogenes converts 2-deoxy-D-gluc-5-ulosonic acid to its monophosphate, 6-phospho-5-dehydro-2-deoxy-D-gluconic acid by transferring a phosphate group from the cofactor, adenosine triphosphate (ATP), which is converted to adenosine diphosphate (ADP). This is part of the breakdown of myo-inositol in this organism.
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:5-dehydro-2-deoxy-D-gluconate 6-phosphotransferase. Other names in common use include 5-keto-2-deoxygluconokinase, 5-keto-2-deoxyglucono kinase (phosphorylating), and DKH kinase.
