ENZYME entry: EC 4.2.1.110
Accepted Name |
Aldos-2-ulose dehydratase.
|
Alternative Name(s) |
1,5-anhydro-D-fructose dehydratase (microthecin-forming). |
AUDH. |
Pyranosone dehydratase. |
Reaction catalysed |
1,5-anhydro-D-fructose <=> 2-hydroxy-2-(hydroxymethyl)-2H-pyran-3(6H)-one + H(2)O |
Comment(s) |
- This enzyme catalyzes two of the steps in the anhydrofructose
pathway, which leads to the degradation of glycogen and starch via
1,5-anhydro-D-fructose.
- Aldose-2-uloses such as 2-dehydroglucose can also act as substrates,
but more slowly.
- This is a bifunctional enzyme that acts as both a lyase and as an
isomerase.
- Differs from EC 4.2.1.111, which can carry out only reaction 1,
is inhibited by its product and requires metal ions for activity.
