Figure 4. The thermal stability analysis of the interfacial secondary structure components in the DegP hexamer.

(a) The SVD-resolved two species-associated spectra centered at 1623 cm⁻¹ and 1629 cm⁻¹. (b) The population thermal titration curves of the structure components (1623 cm⁻¹, 1629 cm⁻¹) retrieved by SVD analysis. (c) The absorbance thermal titration curve at 1651 cm⁻¹ and the population thermal titration curve of the structure component at 1629 cm⁻¹.
