Interaction of E3 with both substrate and E2-Ub, brings them into proximity so that ubiquitin is transferred from E2 to the substrate. In most cases the transfer of ubiquitin is direct from E2 to substrate, but in a small subset of E3s, it occurs via a covalent E3-Ub thioester intermediate (Raymond et al. 2009).
