Figure 3.
Fig. 3. Ubiquitin-binding Site 1 of Tom1-GAT. (A) Stereo
ribbon representation of the interface between Site 1 of
Tom1-GAT (red) and ubiquitin (blue), in the same view as Fig.
1A. Side chains of Tom1-GAT and ubiquitin directly involved in
the interactions are shown in ball-and-stick models with labels.
The salt bridge between Glu256 and Arg42 is indicated by a red
line. (B) The molecular surface of ubiquitin is shown with a
ribbon drawing of GAT, in the same view as (A). Hydrophobic
residues of ubiquitin are colored green. Residues participating
in the interaction are labeled. (C) The molecular surface of GAT
is shown with a line drawing of ubiquitin, in the view rotated
180° about the vertical axis relative to (A).
