UniProtKB description: Participates in the repair of UV-damaged DNA by excising pyrimidine dimers that are the major UV-lesions (PubMed:6254991). DNA glycosylase activity hydrolyzes the glycosylic bond of the 5' pyrimidine of the dimer (PubMed:6254991). This leaves apurinic/apyrimidic (AP) sites in the DNA. These AP sites are removed by the AP lyase activity which cleaves the intrapyrimidine phosphodiester bond (PubMed:6254991). Catalysis proceeds via a protonated imine covalent intermediate between the alpha-amino group of the N-terminal threonine residue and the C1' of the deoxyribose sugar of the 5' pyrimidine at the dimer site (PubMed:16916523, PubMed:8347626).
