Structural Elements of Photosystem II (IMAGE) DOE/SLAC National Accelerator Laboratory Caption Structural elements of photosystem II, a large protein complex involved in photosynthesis. The illustration shows how combining information from continuous diffraction and Bragg peaks yields higher-resolution images with more structural details (right, mesh) compared to images obtained from Bragg peaks only (left, mesh).
