Figure 3.

Orientational autocorrelation of (A) adenosine and (B) UK432097. Data for two independent trajectories of each ligand are shown. The first trajectory results are shown in solid circles and solid line, and the second trajectory results are shown by open circles and dashed line. The circles are obtained from $\langle \mathbf{n}\left(t\right)·\mathbf{n}\left(t+\Delta t\right)\rangle$, as defined in Materials and Methods. The lines are exponential functions of $f\left(\Delta t\right)=a\times exp\left(-\left(\Delta t/\tau \right)\right)+b$, fitted to the circles. The fitted decay constants τ for the adenosine case (A) are 78 ns (72 ns) for the solid (dashed) line, and for the UK432097 case (B) are 17 ns (28 ns) for the solid (dashed) line.
