Maltoza O-acetiltransferaza (EC 2.3.1.79, maltozna transacetilaza, maltozna O-acetiltransferaza, MAT) je enzim sa sistematskim imenom acetil-KoA:maltoza O-acetiltransferaza.^[1]^[2]^[3] Ovaj enzim katalizuje sledeću hemijsku reakciju

acetil-KoA + maltoza

\rightleftharpoons

KoA + 6-O-acetil-alfa-D-glukopiranozil-(1->4)-D-glukoza

Ovaj enzim nije identičan sa EC 2.3.1.18, galaktozid O-acetiltransferazom. Acetil grupa se dodaje samo u C⁶ poziciji glukoze i u C⁶ poziciji neredukujućeg glukoznog ostatka maltoze.
