Temperature scan of Pil Bac1 ΔN using SRCD. A: SRCD spectra with increasing temperature shown with data from 260 to 190 nm. B: Plot of the component curves resulting from principal component analysis of the CD data set in A, with the associated coefficients plotted in C. C: A fit of the coefficients for component 1 (blue) with a sigmoidal function to find the inflection point yields a melting temperature of 36°C, while fitting up to 50°C for component 2 yields a value of 38°C.
