Fig. 5: The ChRmine retinal binding pocket.
From: Cryo-EM structures of the channelrhodopsin ChRmine in lipid nanodiscs
a ChRmine viewed from the membrane plane with position of retinal binding pocket highlighted. b Views of the retinal binding pockets of (top) ChRmine and (bottom) Chrimson. Protein surface is colored from hydrophobic (brown) to hydrophilic (teal). c ChRmine retinal binding pocket with key residues drawn as sticks. d Overlay of ChRmine and Chrimson illustrating differences in packing environment.
