Structures of Hect domains from E3 from ubiquitin-protein ligase E3a and WW domain-containing protein 1. Hect domains from E3a (SCOP d1d5fa_) is on the left and protein 1 (SCOP d1nd7a_) is on the right. The amino acids included in the reference alignment are represented as orange sticks, helices in yellow, strands in blue.
