Macromolecular crystallography at SPring-8 and SACLA.

Abstract

Since the groundbreaking determination of the first protein crystal structure by J. C. Kendrew in 1959, macromolecular crystallography (MX) has remained at the forefront of structural biology, driven by continuous technological advancements. The advent of synchrotron radiation in the 1990s revolutionized the field, enhancing data quality, introducing novel phasing methods, and broadening the scope of target samples to include membrane proteins and supramolecular complexes. In 1997, Japan inaugurated SPring-8, one of the world's largest third-generation synchrotron radiation facilities. With its high-brilliance radiation from insertion devices, SPring-8 has dramatically increased the capability of MX. This paper describes MX's evolution, current developments, and prospects at SPring-8 and SACLA.
