ENZYME entry: EC

Accepted Name
2-dehydro-3-deoxy-phosphogluconate/2-dehydro-3-deoxy-6-phosphogalactonate aldolase.
Alternative Name(s)
2-keto-3-deoxygluconate aldolase.
Reaction catalysed
  • 2-dehydro-3-deoxy-6-phospho-D-gluconate <=> pyruvate + D-glyceraldehyde 3-phosphate
  • 2-dehydro-3-deoxy-6-phospho-D-galactonate <=> pyruvate + D-glyceraldehyde 3-phosphate
  • In the archaeon Sulfolobus solfataricus the enzyme is involved in glucose and galactose catabolism via the branched variant of the Entner-Doudoroff pathway.
  • It utilizes 2-dehydro-3-deoxy-6-phosphate-D-gluconate and 2-dehydro- 3-deoxy-6-phosphate-D-galactonate with similar catalytic efficiency.
  • In vitro the enzyme can also catalyze the cleavage of the non- phosphorylated forms 2-dehydro-3-deoxy-D-gluconate and 2-dehydro-3- deoxy-D-galactonate with much lower catalytic efficiency.
