ENZYME entry: EC

Accepted Name
Uronate dehydrogenase.
Alternative Name(s)
Uronic acid dehydrogenase.
Reaction catalysed
  • Beta-D-galacturonate + NAD(+) <=> D-galactaro-1,5-lactone + NADH
  • Beta-D-glucuronate + NAD(+) <=> D-glucaro-1,5-lactone + NADH
  • The enzyme, characterized from the bacterium Agrobacterium fabrum, participates in oxidative degradation pathways for galacturonate and glucuronate.
  • The enzyme can only accept the beta anomeric form of the substrate.
  • The 1,5 lactone product is rather stable at cytosolic pH and does not hydrolyze spontaneously at a substantial rate.
  • Formerly EC
