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.

  • 'Dancing molecules' heal cartilage damage July 26, 2024
    New therapy uses synthetic nanofibers to mimic the natural signaling of a protein that is crucial for cartilage formation and maintenance. Researchers found that intensifying the motion of molecules within the nanofibers led to more components needed for regeneration. After just four hours, the treatment activated the gene expression necessary to generate cartilage. Therapy could […]
  • New understanding of fly behavior has potential application in robotics, public safety July 26, 2024
    Scientists have identified an automatic behavior in flies that helps them assess wind conditions -- its presence and direction -- before deploying a strategy to follow a scent to its source. The fact that they can do this is surprising -- can you tell if there's a gentle breeze if you stick your head out […]

    Engineering researchers have demonstrated a state-of-the-art hardware device that could reduce energy consumption for artificial intelligent (AI) computing applications by a factor of at least 1,000.
  • New drug shows promise in clearing HIV from brain July 25, 2024
    An experimental drug originally developed to treat cancer may help clear HIV from infected cells in the brain, according to a new study. By targeting infected cells in the brain, drug may clear virus from hidden areas that have been a major challenge in HIV treatment.
