Glukan 1,4-a-glukozidaza (EC 3.2.1.3, glukoamilaza, amiloglukozidaza, gama-amilaza, lizozomalna alfa-glukozidaza, kiselinska maltaza, ekso-1,4-alfa-glukozidaza, glukozna amilaza, gama-1,4-glukanska glukohidrolaza, kiselinska maltaza, 1,4-alfa-D-glukanska glukohidrolaza) je enzim sa sistematskim imenom 4-alfa-D-glukan glukohidrolaza.[1][2][3][4][5][6] Ovaj enzim katalizuje sledeću hemijsku reakciju

hidroliza terminalnih (1->4)-vezanih alfa-D-glukoznih ostataka sukcesivno sa neredukujućih krajeva lanaca uz oslobađanje beta-D-glukoza

Većina formi ovog enzima brzo hidrolizuje 1,6-alfa-D-glukozidne veze.
