6-phospho-2-dehydro-D-gluconic acid

The enzyme characterised from Aerobacter aerogenes converts the hexose sugar, 2-dehydro-D-gluconic acid, to 6-phospho-2-dehydro-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-D-gluconate 6-phosphotransferase. Other names in common use include ketogluconokinase, 2-ketogluconate kinase, ketogluconokinase (phosphorylating), and 2-ketogluconokinase.[2]
