Randomization of the Damaged Base-Capping Loop Rewires Substrate Specificity in Formamidopyrimidine–DNA Glycosylase

Abstract Formamidopyrimidine–DNA glycosylase (Fpg) is a bacterial base excision repair enzyme that removes 8-oxoguanine (8-oxoG) and some other oxidatively damaged nucleobases from DNA. Fpg hydrolyzes the N-glycosidic bond of the damaged nucleotide and nicks DNA at the resulting...
