PG - 337-44 LID - S0969-2126(13)00466-8 [pii] LID - 10.1016/j.str.2013.12.004 [doi] AB - The combination of an E2 ubiquitin-conjugating enzyme with an E3 ubiquitin-ligase is essential for ubiquitin modification of a substrate. Moreover, the pairing dictates both the substrate choice and the modification type. The molecular details of generic E3-E2 interactions are well established. Nevertheless, the determinants of selective, specific E3-E2 recognition are not understood. There are approximately 40 E2s and approximately 600 E3s giving rise to a possible approximately 24,000 E3-E2 pairs. Using the Fanconi Anemia pathway exclusive E3-E2 pair, FANCL-Ube2T, we report the atomic structure of the FANCL RING-Ube2T complex, revealing a specific and extensive network of additional electrostatic and hydrophobic interactions. Furthermore, we show that these specific interactions are required for selection of Ube2T over other E2s by FANCL. CI - Copyright (c) 2014 The Authors. Published by Elsevier Inc. All rights reserved.
