Fig. 1: Overall structure of the KnChR dimer.
From: Cryo-EM structure of a blue-shifted channelrhodopsin from Klebsormidium nitens
a Overall structure of the nanodisc-reconstituted KnChR dimer. The cryo-EM density maps are shown with the two protomers in different colors. b Ribbon representation of KnChR. Each KnChR protomer is depicted in a cartoon model, with the N-terminal region in blue and the C-terminal region in red. The intermolecular disulfide bridge, formed by C28, is shown as a yellow stick. c Superimposition of KnChR and CrChR2 (PDB ID: 6EID). d Characteristic interactions in the N-terminal region.
