Comments
Not identical with EC?3.1.1.1?(carboxylesterase), EC?3.1.1.2?(arylesterase), EC?3.1.1.7?(acetylcholinesterase) or EC?3.1.1.8?(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.
