Breakthrough in Membrane-Protein Design Settles Long-Standing Debate

June 10, 2019

Membrane proteins that connect a cell’s inner workings with the outside world are essential for life and genetic mutations that affect their structural integrity or biological function are the cause of many diseases. Given their importance, researchers are interested in ascertaining the general physics principles underlying how membrane proteins fold and stabilize their molecular structures. Using high-resolution protein crystallography at the Advanced Light Source (ALS) Beamline 8.3.1, scientists from UCSF characterized designed membrane proteins to better understand the forces that stabilize these large, complex structures.

Toward a Blueprint for Anti-influenza Drugs

December 7, 2018

An international team led by researchers at UCSF used protein crystallography at the Advanced Light Source (ALS) beamline 8.3.1 to obtain structures of several influenza antiviral drug molecules bound to their proton-channel targets in both open and closed conformations. These complexes provide the first high-resolution views of how the drugs interact with and disrupt the water-molecule networks lining the M2 transmembrane channel. The structures provide an atomic-level blueprint from which to design more effective anti-influenza drugs that can overcome growing drug resistance. ALS beamline 8.3.1 is operated by James Holton, MBIB beamline scientist and associate adjunct professor at UCSF.

ALS Enables Structural Determination of Respiratory Virus-Antibody Complex

March 9, 2018

Using diffraction data collected at cryogenic temperature at the Advanced Light Source (ALS) Beamline 8.3.1, University of California Santa Cruz (UCSC) scientists, led by assistant professor of biomolecular engineering Rebecca DuBois, determined the three-dimensional atomic structure of a major surface protein of the respiratory syncytial virus (RSV): RSV G. Medical researchers have been trying to develop a vaccine for RSV, which causes serious respiratory disease in infants and older adults, for more than 50 years without success. But by leveraging the work of collaborators at Trellis Bioscience, who isolated protective human antibodies targeting RSV G, an attachment protein that allows the virus to stick to lung cells, the UCSC scientists were able to show that these protective antibodies target a section of the protein called the central conserved domain that is the same in all strains of the virus. The findings, published March 9 in Science Immunology, point to a promising route for designing a vaccine effective against a broad range of RSV strains. Read more from the UC Santa Cruz News Center.

CRISPR Target Recognition Mechanism Illuminated Using Data From ALS

October 18, 2017

Using diffraction data obtained at Berkeley Lab’s Advanced Light Source (ALS) and at the Stanford Synchrotron Radiation Lightsource (SSRL), researchers in Biosciences’ Molecular Biophysics & Integrated Bioimaging (MBIB) division and at UC Berkeley have discovered how CRISPR-associated (Cas) proteins are able to recognize their target locations with such great specificity. X-ray crystallography was used to solve the structures of Cas1 and Cas2—responsible for DNA-snippet capture and integration—as they were bound to synthesized DNA strands designed to mimic different stages of the process. The resulting structures show how the system works in its native context as part of a bacterial immune system, and also inform the development of the CRISPR-Cas system as a general-purpose molecular recording device. Jun-Jie Liu, a joint postdoc in the labs of Jennifer Doudna and Eva Nogales, and Addison Wright, a graduate student in Doudna’s lab, were co-first authors on the paper, published in the journal Science. Read more in this ALS Science Highlight.

NIH Awards $6.5 Million for Augmenting Structural Biology Research Experience

October 16, 2017

The National Institutes of Health (NIH) has awarded $6.5 million to Berkeley Lab to integrate existing synchrotron structural biology resources to better serve researchers. The grant will establish a center based at the Lab’s Advanced Light Source (ALS) called ALS-ENABLE that will guide users through the most appropriate routes for answering their specific biological questions.
