MOESM3 of Spectral tuning mediated by helix III in butterfly long wavelength-sensitive visual opsins revealed by heterologous action spectroscopy

Additional file 3: Figure S3. Locations of amino acid residues different between PxRh1 and PxRh3 in helix III. Seven amino acid residues that are different between PxRh1 and PxRh3 in helix III are marked (red) on the tertiary structure of jumping spider rhodopsin-1 (PDB num: 6I9K) based on the alignment of butterfly opsins and jumping spider rhodopsin-1. The retinal chromophore is displayed in yellow.
