Enzyme Information

3.2.2.27
Uracil-DNA glycosylase.
based on mapping to UniProt P13051
Hydrolyzes single-stranded DNA or mismatched double-stranded DNA and polynucleotides, releasing free uracil.
-!- Uracil-DNA glycosylases are widespread enzymes that are found in all living organisms. -!- Uracil-DNA glycosylase (EC 3.2.2.27) and double-stranded uracil-DNA glycosylase (EC 3.2.2.28) form a central part of the DNA-repair machinery since they initiate the DNA base-excision repair pathway by hydrolyzing the N-glycosidic bond between uracil and the deoxyribose sugar thereby catalyzing the removal of mis-incorporated uracil from DNA.
