The effects of a stomach flu can range from pesky to deadly. Researchers recently used an AI program to predict the structure of a common rotavirus and collaborated with a Biosciences researcher working at the Advanced Light Source to validate their novel finding.
Structural Imaging at ALS Yields New Insights into DNA Repair Enzyme
PARP1 is an enzyme that senses DNA damage and sends a cellular signal to carry out repair. It has been found to be upregulated in several carcinomas and inhibiting its activity has been shown to repress tumor growth and metastasis. PARP1 has also emerged as a promising therapeutic target for Alzheimer and Parkinson diseases, where attenuating the enzyme’s hyperactivity can help cells survive. To better understand the regions of PARP1 that various inhibitors attack, an international team of researchers captured the first snapshot of the enzyme in the active state it adopts after detecting DNA damage.
Cryo-EM Reveals Blueprint for Microbial Photosynthesis
Advances in cryogenic electron microscopy have enabled an international team of experts to visualize the structure of a cyanobacterial phycobilisome with nearly atomic resolution. The work, a collaboration among researchers at Michigan State University, UC Berkeley, Berkeley Lab, and the University of South Bohemia in the Czech Republic, was published in Nature. Knowing the position of different proteins and pigments helps scientist better understand this natural process and can inspire future applications in areas such as renewable energy and environmental remediation.
Protein Structures Aren’t Set in Stone
A new paper from Biosciences researchers in the Environmental Genomics and Systems Biology Division, the Molecular Biophysics and Integrated Bioimaging Division, and the Joint BioEnergy Institute (JBEI) reveals the possibility that many of the proteins we thought we knew actually exist in other, unknown shapes.
R&D 100 Awards Are In!
Seven innovative technologies from Berkeley Lab have been honored with a 2022 R&D 100 Award. Biosciences Area researchers contributed to two different products that were awarded.
