Chains	Enzyme Name	Description	Catalytic Residues
A	double-stranded uracil-DNA glycosylase M-CSA #834	Mismatched base pairing between G and U or G and T is common in DNA replication and would lead to substitution mutations. Therefore the enzyme G/U mismatch-specific DNA glycosylase is vital in preserving the integrity of DNA: it is able to hydrolyse the glycosidic bond to release the uracil or thymine base, thus creating an abasic site which allows the entire nucleotide to be recognised and removed. The enzyme shows significant structural and functional similarity to the well characterised family of Uracil DNA glycosylases which remove uracil wherever it occurs in DNA; however there is very little sequence similarity suggesting that convergent evolution may be responsible for the similarities observed. It is apart of the MUG/TDGs family of uracil-DNA glycosylases along with homologue human thymine-DNA glycosylase of which, has two alternative mechanisms proposed.
