Overview
Aminoacyltransferases are ezymes that catalyse the transfer of an aminoacyl group from donor to acceptor, forming an ester or amide bond. There are 23 sub-families of aminoacyltransferase enzymes including peptidyl transferases, leucyltransferases, transglutaminases, and several families of ubiquitin-conjugating and transferases.

Human RING-type E3 ubiquitin transferases (also known as ubiquitin ligases) include several groupings based on structure and function, of which 70 are tripartite motif (TRIM)-containing proteins. Whilst these 70 share conserved structural domains, they mediate diverse cellular functions.
