The presence of a carbohydrate-rich cell wall is a ubiquitous feature of all plants. While we are beginning to understand the composition and diversity of the polysaccharide components in these walls, little is known about the enzymes involved in their synthesis. By combing macromolecular X-ray crystallography together with solution X-ray scattering data collecting at beamline…

Angela Kayll from James Madison University spent the summer of 2022 at SIBYLS working with our SAXS scientists and collecting SAXS data on Matlodextrin chains. Angela (Angie), was given a Biochemistry and Molecular Biology poster presentation award for this work at the 2022 Annual Biomedical Research Conference for Minority Students in Anaheim, CA. Her poster…

Researchers from Genentech in collaboration with SIBYLS beamline scientist, Michal Hammel, used Small Angle X-Ray scattering to learn how an assembly of three proteins works together to transmit signals for cell division. The work reveals new targets for the development of drugs to fight certain types of cancer, including lung, colorectal, and pancreatic.
SIBYLS beamline scientists Daniel Rosenberg and Michal Hammel collaborated with the Shih Lab at UC Berkeley to study patterns of oligomerization in rubisco, nature’s most abundant carbon-fixing enzyme. By using SEC-SAXS-MALS, they were able to conduct a diversity-driven structural study across extant and ancestral form II rubisco and retrace the evolutionary trajectory taken during the…

SIBYLS beamline scientist, Scott Classen, collaborated with ScienceIT consultants Shawfeng Dong and Fengchen Liu to use AutoML machine learning for the LoopDHS project. As part of the effort, IT student intern Jordan Jung developed a training dataset for the model to improve the accuracy. These developments enabled Dr. Classen to develop loopDHS a custom software…

SIBYLS beamline scientist, Michal Hammel, will lead a workshop on Applications of Small Angle Scattering to Structural Biology at the 2022 ACA in Portland, Oregon on July 29th. Registration is now open.
Analyzing SAXS data collected at SIBYLS beamline 12.3.1, Michal Hammel determined the structural arrangement of the VH and VL domains in the COBRA™ (COnditional Bispecific Redirected Activation) T-cell engagers. The study showed that the structural arrangement of the domains in COBRA is different from the expected yet the stable fold is maintained. Findings provide insights…
