(a) Absorption spectra of WT-PYP in Tris-HCl buffer: glycerol (55:45 v:v) at 77 K (dark solid line). The absorption lineshape is deconvolved into the absorption due to pG and the red photoproduct, PYPB (light solid lines; the original absorption spectrum is shown in the light dashed line). (b) The electroabsorption spectra (dark solid line) and fit (dark dot-dashed line) to the overall absorption lineshape (dark solid line in a) are shown along with the individual contributions of the zeroth (light dotted), first derivative (light dashed), and second derivative (light dot-dashed) components of the absorption spectrum (see Eq. 1). (c) Here the fit to the derivatives of the absorption bands of pG and PYPB (light solid lines in a) is shown. The legend key is the same as in b.
