Figure 3. Model of the E2-Ub Thiolester IntermediateThe model was determined by Monte Carlo docking as described in Experimental Procedures. The model shows (a) side and (b) end orientation views of helix a2 in the E2 molecule. Residues are indicated on both E2 and Ub to indicate important side chain-side chain interactions that arise at the protein-protein interface, as described in the text. In both figures, the thiol-forming C88 residue in E2 is a shown as a yellow ball-and-stick representation near the (a) center and (b) top of the complex
