Determination of the oligomeric state of PufL coiled-coil modified reaction centres. (a) Absorbance spectra of purified WT or PufL-modified reaction centres, normalised to the same absorbance at 800 nm. (b) Analytical gel filtration of multimer fractions from preparative gel filtration. (c) Sedimentation coefficients determined by sedimentation velocity AUC. (d) Sucrose density gradient ultracentrifugation. The red colouration of the protein band arises principally from the single reaction centre carotenoid. For panels b and c colour coding is as for panel a.
