Structural basis of ultraviolet sensitivity and gating in an anion-conducting apusomonad rhodopsin

Wataru Shihoya, Masaki Tsujimura, Hiroto Takahashi…·Osamu Nureki

This study determines the cryo-EM structure of SfApuR2, an ultraviolet-sensitive anion-conducting rhodopsin, and identifies structural features that explain its UV sensitivity and gating mechanism.
