CD spectroscopy reveals that the C-terminal region of Zta contributes to stability of the coiled-coil dimer. (A) CD analysis determining the secondary structure of the M221pep and I231pep (at a concentration of 100 mM), shown by white triangles and black squares, respectively. (B) The melting curve was obtained by measuring a signal obtained at the wavelength of 222 nm for M221pep or I231pep through a range of temperature (from 2°C to 90°C).
