Figure 1
Overall crystal structure of linear Ub2 in a more compact conformation. (a) Crystal structure of two linear Ub2 molecules in compact conformations in the asymmetric unit. (b) The electron-density map around the linker between two Ub moieties is contoured at 1.0σ with 2mFo − DFc coefficients. (c) Superposition of two linear Ub2 structures (molecule A, blue; molecule B, light orange) with the previously reported structure (PDB entry 3axc , green), aligned on the distal moiety. Spheres represent the centres of each ubiquitin moiety. The proximal moieties are shown on the right. |
