In [[enzymology]], an '''acetylsalicylate deacetylase''' ({{EC number|3.1.1.55}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:acetylsalicylate + H<sub>2</sub>O <math>\rightleftharpoons</math> salicylate + acetate

Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[acetylsalicylate]] and [[water|H<sub>2</sub>O]], whereas its two [[product (chemistry)|products]] are [[salicylate]] and [[acetate]].

This enzyme belongs to the family of [[hydrolase]]s, specifically those acting on carboxylic [[ester]] bonds.  The systematic name of this enzyme class is '''acetylsalicylate O-acetylhydrolase'''. Other names in common use include '''aspirin esterase''', '''aspirin esterase''', '''acetylsalicylic acid esterase''', and '''aspirin hydrolase'''.
