ENZYME entry: EC 4.1.2.55

PURL: https://purl.expasy.org/enzyme/EC/4.1.2.55
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 = D-glyceraldehyde 3-phosphate + pyruvate
  • 2-dehydro-3-deoxy-6-phospho-D-galactonate = D-glyceraldehyde 3-phosphate + pyruvate
Comment(s)
  • 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. cf. EC 4.1.2.14 and EC 4.1.2.21.
