Extrahelical bases
WebJun 3, 2014 · Spontaneous flipping of a single DNA base to an extrahelical position is a fundamental issue in DNA biophysics. The dynamics of such spontaneous flipping of a lesion or mismatched base is an important biophysical feature of DNA to discriminate damaged base from normal Watson–Crick paired ones. WebMay 20, 2024 · The process of moving a DNA base extrahelical (base flipping) has been shown in the co-crystal structure of a UV-induced pyrimidine dimer-specific glycosylase, T4 endonuclease V, with its substrate DNA. Compared with other enzymes known to use base flipping, endonuclease V is unique in that it moves the base opposite the target
