  "summary": "Ultraviolet-sensitive anion rhodopsin channels expanded the spectral range of light-gated ion transport, but how they combine a deprotonated retinal Schiff base with anion conduction remains unclear. Here we report the cryo-electron microscopy structure of the apusomonad rhodopsin SfApuR2 and combine constant-pH molecular dynamics with electrophysiological analysis of mutants. The trimeric…",
