Just Accepted Manuscript: Structure Activity Relationships Reveal Key Features of 8-Oxoguanine:Adenine Mismatch Detection by the MutY DNA Glycosylase
7/20/2017
The recently accepted manuscript, Structure Activity Relationships Reveal Key Features of 8-Oxoguanine:Adenine Mismatch Detection by the MutY DNA Glycosylase, was accepted for publication in ACS Chemical Biology.
MutY, remarkably, is able to specifically recognize and initiate repair of target OG:A mismatches from among a vast sea of natural DNA. To help reveal molecular features of OG that are critical for MutY recognition, this work explored the effects of systematic OG:A substrate alterations on MutY recognition in a cellular context. OG analogs were synthesized, assembled into OG:A modified oligonucleotides, and structure activity relationships were investigated using binding and cellular repair assays. Read the article to find out more about how specific OG modifications effect MutY glycosylase activity. Click here for the article: http://pubs.acs.org/doi/abs/10.1021/acschembio.7b00389.

Just Accepted Manuscript: S K-edge XAS Studies of the Effect of DNA Binding on the [Fe4S4] Site in EndoIII and MutY
7/18/2017
Check out the latest manuscript from the David Lab and collaborators: S K-edge XAS Studies of the Effect of DNA Binding on the [Fe4S4] Site in EndoIII and MutY, which was recently accepted for publication in JACS. In this work, the iron-sulfur clusters of DNA repair glycosylases Endonuclease III and MutY were examined using S K-edge X-ray Absorption Spectroscopy (XAS) in order to investigate DNA binding and solvation effects on Fe-S bond covalencies.

- Study of velvet worm slime could revolutionize sustainable material design May 6, 2025A new discovery about the slime ejected by velvet worms could revolutionize sustainable material design. The findings outline how a naturally occurring protein structure, conserved across species from Australia, Singapore and Barbados over nearly 400 million years of evolution, enables the slime's transformation from liquid to fiber and back again. It's a discovery that could […]
- New drone-assisted 3D model offers a more accurate way to date dinosaur fossils May 6, 2025A new study is reshaping how scientists date dinosaur fossils in Alberta's Dinosaur Provincial Park (DPP). Using advanced drone-assisted 3D mapping, researchers have uncovered significant variations in a key geological marker, challenging long-standing methods of determining the ages of dinosaur fossils.
- Two new crocodile species discovered May 6, 2025Biologists have discovered two previously unknown species of crocodiles, one living on the island of Cozumel and the other on the atoll of Banco Chinchorro, both off the Yucat n Peninsula. The findings challenge long-held assumptions about the American crocodile (Crocodylus acutus) and highlight the urgent need for conservation efforts, the researchers say.
- Study suggests we don't just hear music, but 'become it' May 6, 2025Psychologists suggest our brains and bodies don't just understand music, they physically resonate with it. These discoveries, based on findings in neuroscience, music, and psychology, support Neural Resonance Theory (NRT).
- 2024 sea level 'report cards' map futures of US coastal communities May 6, 2025Researchers have released their 2024 U.S. sea level 'report cards,' providing updated analyses of sea level trends and projections for 36 coastal communities. Encompassing 55 years of historical data in a new, interactive dashboard, the report cards aid planning and adaptation efforts by forecasting rates of sea level rise to 2050.
