Superfamily Uracil-DNA glycosylase-like domain
Functional Family G/T mismatch-specific thymine DNA glycosylase

Enzyme Information

3.2.2.29
Thymine-DNA glycosylase.
based on mapping to UniProt Q13569
Hydrolyzes mismatched double-stranded DNA and polynucleotides, releasing free thymine.
-!- Thymine-DNA glycosylase is part of the DNA-repair machinery. -!- Thymine removal is fastest when it is from a G/T mismatch with a 5'-flanking C/G pair. -!- The glycosylase removes uracil from G/U, C/U, and T/U base pairs faster than it removes thymine from G/T.
