  • Time-resolved serial femtosecond crystallography at X-ray free-electron lasers is a powerful approach for studying macromolecular dynamics, but its widespread use is limited by high sample consumption. Here, the authors introduce a segmented-droplet mix-and-inject strategy at the European XFEL that reduces sample consumption by up to 97% while preserving the data quality required for time-resolved structural studies of the enzyme NQO1.

  • Rhodopsins are ubiquitous light-driven membrane proteins that have diverse functions in nature, and value as optogenetics tools. Here the authors characterise type 1 viral channelrhodopsins, showing that they regulate intracellular calcium and can be used for the photocontrol of muscle contraction in vivo.

  • Here, the authors present four high-resolution structures of SyHR protein from cyanobacterial anion pumps family: chloride and sulfate bound forms and two active state structures. These structures provide insights into the molecular mechanisms of SyHR and cyanobacterial anion pumps in general.

  • Proteorhodopsins act as light-driven outward proton pumps mainly at neutral and alkaline pH, however, mirror proteorhodopsins are known to operate only at acidic pH. Here, the authors report the detailed structural and functional characterization of pH mirror proteorhodopsin SpaR as well as its diverse biological roles.
