ENZYME entry: EC

Accepted Name
Gluconate/galactonate dehydratase.
Alternative Name(s)
Gluconate dehydratase.
Reaction catalysed
  • D-gluconate <=> 2-dehydro-3-deoxy-D-gluconate + H(2)O
  • D-galactonate <=> 2-dehydro-3-deoxy-D-galactonate + H(2)O
  • The enzyme is involved in glucose and galactose catabolism via the nonphosphorylative variant of the Entner-Doudoroff pathway in Picrophilus torridus and via the branched variant of the Entner- Doudoroff pathway in Sulfolobus solfataricus.
  • In vitro it utilizes D-gluconate with 6-10 fold higher catalytic efficiency than D-galactonate.
  • Cf. EC and EC
