Abstract

E3 ligases carry out the final step in the ubiquitination cascade, catalyzing transfer of ubiquitin from an E2 enzyme to form a covalent bond with a substrate lysine. Three distinct classes of E3 ligases have been identified that stimulate transfer of ubiquitin and ubiquitin-like proteins through either a direct or an indirect mechanism. Only recently have the catalytic mechanisms of E3 ligases begun to be elucidated.
