Alternansaharaza (EC 2.4.1.140, saharoza-1,6(3)-alfa-glukan 6(3)-alfa-glukoziltransferaza, saharoza:1,6-, 1,3-alfa-D-glukan 3-alfa- and 6-alfa-D-glukoziltransferaza, saharoza:1,6(1,3)-alfa-D-glukan 6(3)-alfa-D-glukoziltransferaza) je enzim sa sistematskim imenom saharoza:(1->6)((1->3))-alfa-D-glukan 6(3)-alfa-D-glukoziltransferaza.^[1] Ovaj enzim katalizuje sledeću hemijsku reakciju

Naizmenično prenosi alfa-D-glukozil ostatake sa saharoze na pozicije 9 i 3 neredukujućeg terminalnog ostatka alfa-D-glukana, čime se formira glukan sa naizmeničnim alfa-(1->6)- i alfa-(1->3)-vezama

Produkt se naziva alternan.
