Endonuclease 8-like 3 (NEIL3)

DNA glycosylase which favors single-stranded DNA (ssDNA), or partially ssDNA structures like bubble and fork structures, to double-stranded DNA (dsDNA). In vitro, displays strong glycosylase activity towards the hydantoin lesions spiroiminodihydantoin (Sp) and guanidinohydantoin (Gh) in both ssDNA and dsDNA; also recognizes FapyA, FapyG, 5-OHU, 5-OHC, 5- OHMH, Tg and 8-oxoA lesions in ssDNA.

No action on 8-oxoG detected. Also shows weak DNA-(apurinic or apyrimidinic site) lyase activity.
