ENZYME entry: EC 1.1.1.292
Accepted Name |
1,5-anhydro-D-fructose reductase (1,5-anhydro-D-mannitol-forming).
|
Alternative Name(s) |
1,5-anhydro-D-fructose reductase. |
AFR. |
Reaction catalysed |
1,5-anhydro-D-mannitol + NADP(+) <=> 1,5-anhydro-D-fructose + NADPH |
Comment(s) |
- Present in some but not all Rhizobium species.
- Differs from hepatic 1,5-anhydro-D-fructose reductase, which yields
1,5-anhydro-D-glucitol as the product (see EC 1.1.1.263).
- In Sinorhizobium morelense, the product of the reaction, 1,5-anhydro-
D-mannitol, can be further metabolized to D-mannose.
- Also reduces 1,5-anhydro-D-erythro-hexo-2,3-diulose and 2-ketoaldoses
(called osones), such as D-glucosone (D-arabino-hexos-2-ulose) and
6-deoxy-D-glucosone.
- Does not reduce common aldoses and ketoses, or non-sugar aldehydes
and ketones.
