| EC | 1.1.1.287 | ||
| Accepted name: | D-arabinitol dehydrogenase (NADP+) | ||
| Reaction: | (1) D-arabinitol + NADP+ = D-xylulose + NADPH + H+ (2) D-arabinitol + NADP+ = D-ribulose + NADPH + H+ |
||
| Other name(s): | NADP+-dependent D-arabitol dehydrogenase; ARD1p; D-arabitol dehydrogenase 1 | ||
| Systematic name: | D-arabinitol:NADP+ oxidoreductase | ||
| Comments: | 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, D-arabinitol 4-dehydrogenase and EC 1.1.1.250, D-arabinitol 2-dehydrogenase, 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. | ||
