| Comments | No activity on DNA containing a T/G mispair or single-stranded DNA containing either a site-specific uracil or 3,N4-ethenocytosine residue [2], significant role for double-stranded uracil-DNA glycosylase in mutation avoidance in non-dividing?Escherichia coli?[3]. 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 hydrolysing the?N-glycosidic bond between uracil and the deoxyribose sugar thereby catalysing the removal of mis-incorporated uracil from DNA. |
