This study investigates the structural basis of near-infrared absorption and noncanonical photoisomerization in neorhodopsin using crystallographic, spectroscopic, and theoretical methods.

This paper resolves the mechanism of covalent bond formation in a LOV photoreceptor using time-resolved crystallography and spectroscopy, revealing a water-mediated proton transfer that accelerates the reaction by fourteen orders of magnitude.

This paper reports crystal structures of a far-red CBCR in three light-absorbing states, revealing new insights into spectral tuning and light signaling mechanisms through protein-chromophore interactions.

The paper reports light energy transfer from hydroxylated carotenoids to heimdallarchaeial rhodopsins in marine archaea, showing light-harvesting capabilities in archaea similar to bacterial rhodopsins.

This study uses time-resolved crystallography and MD simulations to reveal structural changes in C1C2 channelrhodopsin during activation, showing how conformational shifts enable ion conduction.
