Abstract
Disclosed herein are methods of producing hexoses from saccharides by enzymatic processes. The methods utilize fructose 6-phosphate and at least one enzymatic step to convert it to a hexose.
Claims9
An enzymatic process for preparing fructose from a starch derivative, the process comprising the steps of:
- (i) converting a starch derivative to glucose 1-phosphate (G1P) using an alpha glucan phosphorylase (αGP);
- (ii) converting G1P to glucose 6-phosphate (G6P) using a phosphoglucomutase (PGM);
- (iii) converting G6P to fructose 6-phosphate (F6P) using a phosphoglucoisomerase (PGI);
- and
- (iv) converting F6P to fructose using a fructose 6-phosphate phosphatase (F6PP).
