Not identical with EC 184.108.40.206 (carboxylesterase), EC 220.127.116.11 (arylesterase), EC 18.104.22.168 (acetylcholinesterase) or EC 22.214.171.124 (cholinesterase). The activity of the liver cytosol enzyme is highest with acetyl esters of aryl alcohols, and thioesters are also hydrolysed; the microsomal enzyme also hydrolyses some other negatively charged esters, with highest activity on esters of salicylate with long-chain alcohols.
