Figure 2

Structural environment of the fluorophore and caged GTP in p21(mod). Stereo representation of the structural environment for the NBD fluorophore and the 2-nitrophenylethyl group of caged GTP in p21(mod)•R-caged GTP (magenta sticks) and p21(mod)•S-caged GTP (green sticks). The aromatic moieties form a strong cation-π/π - π stacking interaction with two residues from a neighboring molecule (Arg102 and Tyr64). For a better representation, only one sub-conformation of each structure is shown.
