Activities description

The Protein Crystal Analysis Division is mainly responsible for the development and maintenance of the research environment for structural biology using the high-brilliance synchrotron radiation at SPring-8. Our Division also develops the advanced research environment to promote structural biology research aimed at elucidating biological systems.
We support academic research by maintaining and upgrading the public beamlines, Structural Biology I (BL41XU: Undulator) and Structural Biology III (BL45XU: Undulator).
In addition, in order to meet the increasing needs of users and to promote the use of the beamline, we are upgrading the following items,

(1) Development of methods to automate and remotely use experiments to speed up structural decisions
(2) Development of instruments aimed at application to samples that are difficult to analyze in the past (e.g., microcrystals and ultra-high resolution structure determination)

In addition, we are conducting crystal structure analysis of proteins, metalloproteins, and viruses in the cellular signaling system as a group to advance structural biology research and develop advanced analysis methods.
