Figure 8.

Alanine scan of the aromatic core. (A) δW57A. (Top) Example currents from a single-site, αδ-only AChR (3 mM ACh; 70 mV; open is up). (Bottom) Cluster PO and interval duration histograms. Only one PO population is apparent (KdACh given in Table 1). (B) Example currents from other alanine mutants. Multiple modes are apparent (two-site, adult AChRs; 30 µM ACh; −100 mV; open is down). αP197A was present for all.
