Tryptophan emission of Y490A apoHtaA-CR2 as a function of GdnHCl concentration. The reaction was in 50 mM Tris-HCl pH 7.0. Data points were recorded after chemical equilibration (5 - 20 min). Solid points are photon counts per second at 340 nm, and the solid line is the fit using the function in Eq. 3.
