Contacts at the UBA–UBL interface. (a) Schematic representation of UBL (cyan) and UBA (green) showing the contact regions between UBA residues from the end of α1 helix, the α1/α2 loop and the α3 helix with residues from UBL from the β3, β4 and β5 strands. (b) Details of the contacts using the same colouring scheme as in (a). All residues from UBA and UBL that make contacts of <4.5 Å are shown. These are UBA residues D341, M342, G343, F344, Q362, L365, D366, L369 and G371 and UBL residues R43, I45, S47, G48, I50, H69, V71 and K72. The view is rotated ∼90° about the vertical axis from (a). (c) The van der Waals surface of UBL as seen by the UBA molecule with the UBA molecule and interacting residues superimposed. The hydrophobic potential (Goodford, 1985 ![]() |
