The TMs of the light scattering, PIA excimer fluorescence, and unfolding.

aTM is the value for half maximal dissociation of tropomyosin from F-actin or the 50% decrease in light scattering (Figures 4, 5).bThe value is the absolute maximum of the excimer peak in the presence of F-actin (Figures 4, 5).cTM is the point at which 50% of tropomyosin is unfolded (Figure 2). Values in parentheses are unlabeled tropomyosins, except in the case of the Excimer Peak column in which values in ( ) are in the absence of F-actin.
