Atomistic Insight into the Role of Threonine 127 in the Functional Mechanism of Channelrhodopsin-2 [PDF]
, 2019 Channelrhodopsins (ChRs) belong to the unique class of light-gated ion channels. The structure of channelrhodopsin-2 from Chlamydomonas reinhardtii (CrChR2) has been resolved, but the mechanistic link between light-induced isomerization of the ...

Early evolution of purple retinal pigments on Earth and implications for exoplanet biosignatures
, 2018 We propose that retinal-based phototrophy arose early in the evolution of life on Earth, profoundly impacting the development of photosynthesis and creating implications for the search for life beyond our planet.
