Sysname
1,5-anhydro-D-mannitol:NADP+ oxidoreductase
Reaction(IUBMB)
1,5-anhydro-D-mannitol + NADP+ = 1,5-anhydro-D-fructose + NADPH + H+ [RN:R08194]
Reaction(KEGG)
Substrate
1,5-anhydro-D-mannitol [CPD:C16538];
NADP+ [CPD:C00006]
Product
1,5-anhydro-D-fructose [CPD:C06485];
NADPH [CPD:C00005];
H+ [CPD:C00080]
Comment
This enzyme is present in some but not all Rhizobium species and belongs in the GFO/IDH/MocA protein family [2]. This enzyme 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 [1]. The enzyme 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. It does not reduce common aldoses and ketoses, or non-sugar aldehydes and ketones [1].
