EC 2.3 Acyltransferases
This subclass contains enzymes that transfer acyl groups, forming either esters or amides. In most cases, the donor is the corresponding acyl-CoA derivative. Sub-subclasses are based on the acyl group that is transferred: acyl groups other than amino-acyl groups (EC 2.3.1), aminoacyltransferases (EC 2.3.2) and acyl groups that are converted into alkyl groups on transfer (EC 2.3.3).
