EC 2.3.1.26     
Accepted name: sterol O-acyltransferase
Reaction: acyl-CoA + cholesterol = CoA + cholesterol ester
Other name(s): cholesterol acyltransferase; sterol-ester synthase; sterol-ester synthetase; sterol-ester synthase; acyl coenzyme A-cholesterol-O-acyltransferase; acyl-CoA:cholesterol acyltransferase; ACAT; acylcoenzyme A:cholesterol O-acyltransferase; cholesterol ester synthase; cholesterol ester synthetase; cholesteryl ester synthetase
Systematic name: acyl-CoA:cholesterol O-acyltransferase
Comments: The animal enzyme is highly specific for transfer of acyl groups with a single cis double bond that is nine carbon atoms distant from the carboxy group.
