ENZYME entry: EC 1.1.1.287
Accepted Name |
D-arabinitol dehydrogenase (NADP(+)).
|
Alternative Name(s) |
D-arabinitol dehydrogenase 1. |
NADP(+)-dependent D-arabinitol dehydrogenase. |
Reaction catalysed |
- D-arabinitol + NADP(+) <=> D-xylulose + H(+) + NADPH
- D-arabinitol + NADP(+) <=> D-ribulose + H(+) + NADPH
|
Comment(s) |
- The enzyme from the rust fungus Uromyces fabae can use D-arabinitol
and D-mannitol as substrates in the forward direction and D-xylulose,
D-ribulose and, to a lesser extent, D-fructose as substrates in the
reverse direction.
- This enzyme carries out the reactions of both EC 1.1.1.11 and
EC 1.1.1.250, but unlike them, uses NADP(+) rather than NAD(+) as
cofactor.
- D-Arabinitol is capable of quenching reactive oxygen species involved
in defense reactions of the host plant.
