FunFam 10: G/U mismatch-specific DNA glycosylase

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Double-stranded uracil-DNA glycosylase. [EC: 3.2.2.28]
Specifically hydrolyzes mismatched double-stranded DNA and polynucleotides, releasing free uracil.
  • No activity on DNA containing a T/G mispair or single-stranded DNA containing either a site-specific uracil or 3,N(4)-ethenocytosine residue, significant role for double-stranded uracil-DNA glycosylase in mutation avoidance in non-dividing Escherichia coli.
  • 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.
