Una acetilesterasa (EC 3.1.1.6) es una enzima que cataliza la siguiente reacción química:


un éster acético + H
2O ⇌displaystyle rightleftharpoons un alcohol + acetato

Por lo tanto los dos sustratos de esta clase de enzimas son un éster acético y agua; mientras que sus dos productos son un alcohol y acetato.
