From: Selenium single-wavelength anomalous diffraction de novo phasing using an X-ray-free electron laser
Final 2Fo-Fc electron-density map of selenobiotin-binding pocket contoured at the 1σ level. Selenobiotin is shown in balls and sticks model and its electron-density coloured in blue. The locations of active site residues are shown and their electron-density is coloured in grey.
