Webb7 apr. 2024 · Another candidate is thymine glycol (Tg), which is a reported NER substrate as well ( 30 ). Both types of cyclopurine lesions and thymine glycol can be generated in DNA by reactions with hydroxyl radicals, which arise through radiolytic decay of water or by Fenton-like reactions of hydrogen peroxide ( 31–34 ). WebbIn this study, both human NEIL1 and NEIL3 have been expressed and purified from E. coli, and the DNA glycosylase activity of these two proteins confirmed using single- and …
