Principle:
(desulphation)
(1)Glucosaminesulphate→D-glucosamine+sulphate
(deacetylation)
(2)N-AcetylGlucosamine→D-glucosamine+acetate
(hexokinase)
(3)D-Glucosamine+ATP→D-glucosamine-6-P+ATP
(glucosamine6-phosphatedeaminase)
(4)D-Glucosamine-6-P+H2O→ D-fructose-6-P+NH4+
(phosphoglucoseisomerase)
(5) F-6-P → G-6-P
(glucose-6-phosphatedehydrogenase)
(6)G-6-P+NADP+→gluconate-6-phosphate+NADPH+H+
