Application

Erlose, a triose sugar (trisaccharide), is used in studies on dietary preference and utilization of triose sugars from aphid honeydew by various insects, such as honey bees and ants. Erlose may be used as a reference compound in assays that analyze the sugars of foods such as royal jelly and honey.[1][2]

An isomelezitose synthase was redesigned out of the sucrose isomerase from Protaminobacter rubrum for the synthesis of isomelezitose (6-O(F)-glucosylsucrose), a potential nutraceutical. The variants F297A, F297P, R333K, F321A_F319A and E428D catalyze the formation of isomelezitose in up to 70 %
