Table I. Spectroscopic details of the major Mn- and Fe-containing fractions.
Spectroscopic details of fractions Mn1 and Fe1 characterized by their retention times (rTs) from the size exclusion chromatogram (Fig. 3A). From the spectra of each peak (Supplemental Fig. S4), the A480 to A410 and the A700 to A670 ratios were calculated, and the wavelength of the maximum absorption (λmax) in the red absorption region of the Chl was determined. Values are based on a single but typical chromatogram of α-DM-solubilized thylakoids using Bis-Tris as the mobile phase.
