Figure 7. Detailed view of the interface of the Ub[2] solution structure. Residues involved in hydrophobic non-bonded contacts (ball-and-stick and transparent CPK representation) or in inter-domain hydrogen bonds or salt-bridges (ball-and-stick representation) are shown (see also Supporting Table 3S; note that for a better visualization not all contacts are shown). Dotted lines represent hydrogen bonds. The residues are labeled with one-letter residue code and residue number, followed by D or P to indicate the distal or proximal domain, respectively.
