Other name(s): KDG kinase (ambiguous); KDGK (ambiguous); 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
Comments: 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.
