Enzyme Information
| 1.1.1.292 |
1,5-anhydro-D-fructose reductase (1,5-anhydro-D-mannitol-forming).
based on mapping to UniProt Q2I8V6
1,5-anhydro-D-mannitol + NADP(+) = 1,5-anhydro-D-fructose + NADPH.
-!- 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.
