the use of alpha-d-glucosidase ( maltase ) [ ec 3.2.1.20 ] of saccharomyces carlsbergensis and oligo-1,6-glucosidase ( isomaltase ) [ ec 3.2.1.10 ] of bakers ' yeast as coupled enzymes differentiates between the two reactions , because alpha-d-glucosidase liberates p-nitrophenol from both p-nitrophenyl alpha-glucoside and p-nitrophenyl alpha-maltoside , but oligo-1,6-glucosidase liberates it only from p-nitrophenyl alpha-glucoside .
