| Abstract: | Glucose isomerase(GI)can catalyze the isomerization of D-glucose to D-fructose,and be considered as one of the most important enzymes applied in the production of high fructose corn syrup(HFCS).In this review,the characteristics of GI,including origin,class,structure,and catalytic mechanism are briefly introduced.Furthermore,it summarizes the improvement of GI catalytic performance,construction of genetically engineered strains and GI immobilization,which are seen as the key techniques and strategies applied in HFCS production with GI. |
