De novo docking models for the UBA(1)-Ub and UBA(2)-Ub interaction. Left panel: Ribbon sketch with the structure of UBA(1) (a) and UBA(2) (b) displayed by a color ramp blue to red (N-terminus to C-terminus). Right panel: Interface between UBA(1) (a) and UBA(2) (b) and Ub. The surface of Ub is shown in atom color; the residues of either UBA domain in contact with Ub are shown and labeled.
