ID 1.1.1.292 DE 1,5-anhydro-D-fructose reductase (1,5-anhydro-D-mannitol-forming). AN 1,5-anhydro-D-fructose reductase. AN AFR. CA 1,5-anhydro-D-mannitol + NADP(+) = 1,5-anhydro-D-fructose + H(+) + NADPH. CC -!- Present in some but not all Rhizobium species. CC -!- Differs from hepatic 1,5-anhydro-D-fructose reductase, which yields CC 1,5-anhydro-D-glucitol as the product (see EC 1.1.1.263). CC -!- In Sinorhizobium morelense, the product of the reaction, 1,5-anhydro- CC D-mannitol, can be further metabolized to D-mannose. CC -!- Also reduces 1,5-anhydro-D-erythro-hexo-2,3-diulose and 2-ketoaldoses CC (called osones), such as D-glucosone (D-arabino-hexos-2-ulose) and CC 6-deoxy-D-glucosone. CC -!- Does not reduce common aldoses and ketoses, or non-sugar aldehydes CC and ketones. DR Q2I8V6, AFR_ENSAD ; Q92KZ3, AFR_RHIME ; //
