Function

[UNG_HHV11] Excises uracil residues from the DNA which can arise as a result of misincorporation of dUMP residues by DNA polymerase or deamination of cytosine. Therefore may reduce deleterious uracil incorporation into the viral genome, particularly, in terminally differentiated neurons which lack DNA repair enzymes.^[1] ^[2]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.

Publication Abstract from PubMed

The 1.75-A crystal structure of the uracil-DNA glycosylase from herpes simplex virus type-1 reveals a new fold, distantly related to dinucleotide-binding proteins. Complexes with a trideoxynucleotide, and with uracil, define the DNA-binding site and allow a detailed understanding of the exquisitely specific recognition of uracil in DNA. The overall structure suggests binding models for elongated single- and double-stranded DNA substrates. Conserved residues close to the uracil-binding site suggest a catalytic mechanism for hydrolytic base excision.

The structural basis of specific base-excision repair by uracil-DNA glycosylase.,Savva R, McAuley-Hecht K, Brown T, Pearl L Nature. 1995 Feb 9;373(6514):487-93. PMID:7845459^[3]
