2-keto-3-deoxy-D-gluconate kinase [ambiguous]
Systematic name:
ATP:2-dehydro-3-deoxy-D-gluconate/2-dehydro-3-deoxy-D-galactonate 6-phosphotransferase



The enzyme from the archaeon Sulfolobus solfataricus is involved in glucose and galactose catabolism via the branched variant of the Entner-Doudoroff pathway. It phosphorylates 2-dehydro-3-deoxy-D-gluconate and 2-dehydro-3-deoxy-D-galactonate with similar catalytic efficiency. cf. EC, 2-dehydro-3-deoxygluconokinase and EC, 2-dehydro-3-deoxygalactonokinase.
