FIGURE 2.
Effect of temperature on the CD spectra of T. thermophilus CuA (TtCuA) in the visible region showing bands from the di-copper center at pH 6.5 in presence of 4 M GuHCl. Inset shows the far-UV CD spectra of the protein, which is characteristic of β-barrel protein. Protein concentration was 23.2 μM. Temperature range was 20–95°C and the arrows show the direction of increasing temperature.
