Glucosidase (glucoamylase,amyloglucosidase)<br />
3.2.1.20 α-D-Glucosidase<br />

Systematic name Origin b<br />
1, 4-α-D-Glucan<br />
glucohydrolase<br />
α-D-Glucoside<br />
glucohydrolase<br />
Pullulan 6-glucanohydrolase<br />
Reactions catalyzed<br />
��<br />
A, B, Hydrolysis of terminal 1, 4-linked<br />
F, Y α-D-glucose residues, successively,<br />
from nonreducing ends producing β-<br />
D-glucose. Most forms of the enzyme<br />
also hydrolyze 1, 6-α-D-Glucosidic<br />
bonds next to an α-1, 4 linkage.<br />
More rapid action on poly- than on<br />
oligosaccharides.<br />
A, B, Hydrolysis of terminal,<br />
F, P, Y Nonreducing 1, 4-linked α-Dglucose<br />
residues with release of, α-<br />
D-glucose. Action on<br />
polysaccharides, if any, is very slow<br />
compared with oligosaccharides.<br />
B, P Hydrolysis of 1, 6-α-D-Glucosidic<br />
linkages in pullulan, amylopectin, and<br />
in α- and β- amylase limit dextrins<br />
of amylopectin. Limited action on<br />
glycogen.
