1. An improved process for the enzymatic production of a hexose, wherein the improved process comprises:
a) converting glucose 1-phosphate (G1P) to glucose 6-phosphate (G6P), catalyzed by a higher activity phosphoglucomutase (PGM), wherein the higher activity PGM results in an improved process that, when the hexose is fructose, produces at least 800% more fructose relative to a process to produce fructose under equivalent process conditions in which the conversion of G1P to G6P is catalyzed by a PGM corresponding to Uniprot ID Q68BJ6 from Thermococcus kodakaraensis;
b) converting the G6P to fructose 6-phosphate (F6P), catalyzed by a phosphoglucoisomerase (PGI); and
c) enzymatically converting the F6P to the hexose, catalyzed by an epimerase, an isomerase, a phosphatase, or a combination thereof.
