Abstract:
A method for preparing glucosamine includes the steps of converting fructose-6-phosphate (F6P) and an ammonium salt to glucosamine-6-phosphate (GlcN6P) under the catalysis of glucosamine-6-phosphate deaminase (EC 3.5.99.6, GlmD); and producing glucosamine (GlcN) by the dephosphorylation of GlcN6P under the catalysis of an enzyme capable of catalyzing the dephosphorylation. Such a method can be used to prepare glucosamine by in vitro enzymatic biosystem.
