Abstract: The fluorescent protein Dronpa undergoes reversible photoswitching reactions between the bright ‘on’ and dark ‘off’ states via photoisomerisation and proton transfer reactions. We report the room temperature crystal structure of the fast switching Met159Thr mutant of Dronpa at 2.0 Å resolution in the bright on state. Structural differences with the wild type include shifted backbone positions of strand β8 containing Thr159 as well as an altered A-C dimer interface involving strands β7, β8, β10, and β11. The M…
