IUBMB Enzyme Nomenclature

EC 3.1.1.13

Accepted name: sterol esterase

Reaction: A steryl ester + H2O = a sterol + a fatty acid

Other name(s): cholesterol esterase; cholesteryl ester synthase; triterpenol esterase; cholesteryl esterase; cholesteryl ester hydrolase; sterol ester hydrolase; cholesterol ester hydrolase; cholesterase; acylcholesterol lipase

Systematic name: steryl-ester acylhydrolase

Comments: A group of enzymes of broad specificity, acting on esters of sterols and long-chain fatty acids, that may also bring about the esterification of sterols. Activated by bile salts.
