| Official Name |
|---|
| Inositol-3-phosphate synthase.
|
| Alternative Name(s) |
|---|
| 1L-myo-inositol-1-phosphate lyase (isomerizing). |
| D-glucose 6-phosphate cycloaldolase. |
| Glucocycloaldolase. |
| Glucose 6-phosphate cyclase. |
| Inositol 1-phosphate synthetase. |
| Myo-inositol-1-phosphate synthase. |
| Reaction catalysed |
|---|
| D-glucose 6-phosphate <=> 1D-myo-inositol 3-phosphate |
| Cofactor(s) |
|---|
| NAD.
|
| Comment(s) |
|---|
| The NAD(+) dehydrogenates the -CHOH- group to -CO- at C-5 of the
glucose 6-phosphate, making C-6 into an active methylene, able to
condense with the -CHO at C-1; finally, the enzyme-bound NADH
reconverts C-5 into the -CHOH- form.
