additional information | Saccharomyces cerevisiae | glucoamylase is an exoglycosidase responsible for hydrolyzing the terminal alpha-1,4 glucosidic bonds of dextrins and related oligo- and polysaccharides, the reaction involves a proton transfer by acid catalysis, followed by formation of a transition state analogous to an oxocarbonium ion, and finally, a base-catalyzed nucleophilic attack of water, glutamic acid present in different regions of the enzyme-active site acts as the acid and base catalysts required for the reaction | ? | - |
