Figure 3. Complex Structure of E2-25K UBA domain with Ub.

Figure 3

Ribbon representation of the lowest energy complex structure, UBA shown on the left, monoUb shown on the right. Sidechains involved in binding are shown as sticks (UBA: M172, G173, F174, L198 ; Ub: R42, I44, K48, Q49, L71, R72). Surface model of the UBA domain with Ub-binding residues highlighted in black, and surface model of Ub with UBA-binding residues highlighted in black are shown below. Molecules have been rotated outward 90° to expose binding surfaces.
