additional information | Aspergillus flavus | glucoamylase is an exo-acting enzyme that yields beta-D-glucose from the nonreducing ends of starch and related oligo- and polysaccharide chains by hydrolyzing alpha-1,4 and alpha-1,6 linkages. The enzyme is able to completely hydrolyze starch if incubated for extended periods of time and hence called the saccharifying enzyme | ? | - |
