CD spectra and small angle X-ray scattering curves of WT and M61A PA cyt <i>c</i>₅₅₁.

<p>(A) CD spectra of oxidized monomeric WT (red) and M61A (green) PA cyt <i>c</i>₅₅₁. Measurement conditions: Sample concentration, 10 μM (heme unit); buffer, 50 mM potassium phosphate buffer; pH, 7.0; temperature, room temperature. (B) Small angle X-ray scattering curves of oxidized monomeric WT (red) and M61A (green) PA cyt <i>c</i>₅₅₁ shown by Kratky plots. The intensities are normalized at their maximum intensities. Measurement conditions: sample concentration, 500 μM (heme unit); buffer, 50 mM potassium phosphate buffer; pH, 7.0; temperature, 20°C.
