ENZYME entry: EC 3.1.1.55

Accepted Name
Acetylsalicylate deacetylase.
Alternative Name(s)
Aspirin esterase.
Reaction catalysed
Acetylsalicylate + H(2)O <=> salicylate + acetate
Comment(s)
  • Not identical with EC 3.1.1.1, EC 3.1.1.2, EC 3.1.1.7 or EC 3.1.1.8.
  • The activity of the liver cytosol enzyme is highest with acetyl esters of aryl alcohols, and thioesters are also hydrolyzed.
  • The microsomal enzyme also hydrolyzes some other negatively charged esters.
  • Best substrates were esters of salicylate with long-chain alcohols.
