Figure 4.
Fig. 4. GTP  S bound to
RhoA^V14. A cartoon of GTP S binding
to RhoA^V14 with Mg2+ and water molecules. All dashed lines
correspond to hydrogen bonding interactions (distance less than
3.5 Å), and the corresponding distances (Å) are
indicated. The residues whose main chains participate in the
hydrogen bonding are represented by rectangles, and the residues
whose side chains participate in the hydrogen bonding are
represented by ovals. The coordination bonds to the Mg2+ ion are
indicated by arrows. The possible hydrogen bond between Gln63
and Wat-3 has a longer distance (3.8 Å). The hydrogen
bonds observed in the current structure but not in H-Ras are
highlighted in red.
