ENZYME entry: EC 1.1.99.28
| Accepted Name |
|---|
| glucose-fructose oxidoreductase.
|
| Reaction catalysed |
|---|
| D-fructose + D-glucose <=> D-glucono-1,5-lactone + D-sorbitol |
| Comment(s) |
|---|
- D-mannose, D-xylose, D-galactose, 2-deoxy-D-glucose and L-arabinose
will function as aldose substrates, but with low affinities.
- The ketose substrate must be in the open-chain form.
- The apparent affinity for fructose is low, because little of the
fructose substrate is in the open-chain form.
- Xylulose and glycerone (dihydroxyacetone) will replace fructose,
but they are poor substrates.
- The enzyme from Zymomonas mobilis contains tightly bound NADP(+).
