Room temperature and serial crystallography and dynamics

Chairs: Sebastian Günther (DESY, Hamburg, DE), Dean Lang (MAX IV, Lund, SE)

Understanding the atomistic motions of macromolecules by crystallography historically relies on inferring its movements as the molecule transitions between an ensemble of stable and metastable states that can be cryo-trapped. But this method cannot reveal motions between higher-energy states and presumes the energy landscape at cryo-temperatures does not differ from that under physiological conditions. Serial and ambient-temperature crystallography are becoming a standard method for resolving high-resolution structures at modern x-ray sources and the derived structures provide complimentary data to those obtained using traditional cryo-crystallography while maintaining the protein nearer to its physiological state. Combining these methods with reaction-initiation techniques such as photoactivation or mixing has also enabled us to observe the dynamic motions of macromolecules from femtoseconds to seconds. This microsymposium will focus on recent scientific and methodological developments in all areas of serial, ambient temperature and time-resolved crystallography and how these lead to an improved understanding of macromolecular function.
