Thermal denaturation of VP1-Z, wtVP1, and protein Z. Structural changes of VP1-Z (open circle), protein Z (triangles), and wtVP1 (filled circle) at protein concentrations of 200 μg/mL, respectively, in 20 mM Tris at pH 7.4, 5% glycerol, 200 mM NaCl, 0.5 mM EDTA were analyzed by CD at 220 nm and a heating rate of 1° C/min.
