Reaction scheme for the conversion of p-nitrophenyl-β-d-glucoside to hexyl-β-glucoside (transglycosylation), with conversion to glucose (hydrolysis) being the side reaction. When d-glucose is used as the glycosyl donor, formation of hexyl-β-glucoside is possible through a condensation reaction (reverse hydrolysis). E-COOH, enzyme.
