Extended Data Fig. 5: Biophysical characterization of diverse marine HeimdallRs with lutein, diatoxanthin or fucoxanthin.
From: Structural insights into light harvesting by antenna-containing rhodopsins in marine Asgard archaea
Absorbance change (up) and fluorescence excitation spectra (bottom) of HeimdallR1, 2 and 3 upon incubation with (orange) or without (purple) lutein (a), diatoxanthin (b), and fucoxanthin (c); emissions were recorded at 720 nm. The results for HeimdallR1 (also shown in Figs. 1 and 3) are shown for reference.
