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.
