ENZYME entry: EC 1.1.1.203
| 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
|
| Cofactor(s) |
|---|
| Mg(2+).
|
| Comment(s) |
|---|
- 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 1.2.1.35.
