ENZYME entry: EC 3.2.2.28

PURL: https://purl.expasy.org/enzyme/EC/3.2.2.28
Accepted Name
double-stranded uracil-DNA glycosylase
Alternative Name(s)
dsUDG
Reaction catalysed
Specifically hydrolyzes mismatched double-stranded DNA and polynucleotides, releasing free uracil
Comment(s)
  • 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.
