The DNA lesions resulting from deamination or oxidation of bases are generally repaired by the base excision repair pathway initiated by damage-specific DNA glycosylases. Single-strand selective monofunctional uracil-DNA glycosylase (SMUG1) present in vertebrates and insects excises not only uracil but also uracil derivatives bearing an oxidized group at ring-C5 from DNA, indicating roles in the repair of both deamination and oxidation damage to DNA. In the present study, we have constructed a series of active site mutants of human SMUG1 and analyzed the catalytic and precision damage recognition mechanisms.
