Abstract
The current disclosure provides a process for enzymatically converting a saccharide into tagatose. The invention also relates to a process for preparing tagatose where the process involves converting fructose 6-phosphate (F6P) to tagatose 6-phosphate (T6P), catalyzed by an epimerase, and converting the T6P to tagatose, catalyzed by a phosphatase.
Claims15
An enzymatic process for preparing tagatose from a starch derivative, the process comprising the steps of:
- (i) converting a saccharide to glucose 1-phosphate (G1P) using alpha glucan phosphorylase (αGP), wherein the saccharide is selected from one or more derivatives of starch;
- (ii) converting G1P to glucose 6-phosphate (G6P) using a phosphoglucomutase (PGM);
- (iii) converting G6P to fructose 6-phosphate (F6P) using a phosphoglucoisomerase (PGI);
- (iv) converting fructose 6-phosphate (F6P) to tagatose 6-phosphate (T6P) catalyzed by a fructose 6-phosphate epimerase (F6PE);
- and
- (v) converting the T6P produced to tagatose catalyzed by a tagatose 6-phosphate phosphatase (T6PP)
- wherein steps (i)-(v) are conducted in a single reaction vessel.
