Data of fixed-target pink-beam serial synchrotron crystallography at the Pohang Light Source II.

Abstract

Pink-beam serial synchrotron crystallography (SSX) is beneficial in terms of X-ray flux and overcoming partial reflection compared with SSX using a monochromatic beam. The fixed-target (FT) scanning method can minimize the physical damage on the crystal sample when delivering the crystals to the X-ray interaction point. Additionally, general researchers can easily access the experiment since no specialized sample transfer technology is needed. The fixed-target pink-beam SSX at the 1C beamline at the Pohang Light Source II (PLS-II) was previously demonstrated using a newly developed magnetic-based sample holder. The room-temperature structure of glucose isomerase and lysozyme were determined using FT pink-beam SSX. Meanwhile, the SSX dataset for glucose isomerase and lysozyme images containing the high X-ray background and multi-crystal hits. These data can be tentatively used to develop an indexing algorithm and practice processing the SX data. This study used detailed information on the diffraction data of fixed-target pink-beam SSX at PLS-II to access the raw data and process the information.
