How is a molecular machine assembled?

The conversion of light into chemical energy by plants and photosynthetic microorganisms is one of the most important processes in nature, removing climate-damaging CO2 from the atmosphere. Protein complexes, so-called photosystems, play the key role in this process. An international research team shed light for the first time on the structure and function of a transition state in the synthesis of photosystem II.
