Representations of the dynamic properties of Rho and its P48A mutant.

A sausage representation of the backbone dynamics of (A) Rho and (B) its P48A mutant. The diameter of the sausage is inversely proportional to the generalized order parameter of the corresponding residue. The side chains of P48/A48, R49, and D51 are shown. The magnitudes of the generalized order parameter are blue, white, and red. A representation of the effective internal correlation times of (C) Rho and (D) its P48A mutant. The residues containing the effective internal correlation times (τe)>500 ps, >50 ps, and <50 ps are shown in dark pink, light pink, and black. The residues without relaxation data and the fitting model are shown in white.
