Protein

Uracil-DNA glycosylase

Gene

UNG

Organism
Epstein-Barr virus (strain B95-8) (HHV-4) (Human herpesvirus 4)
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Experimental evidence at protein leveli

Functioni

Excises uracil residues from the DNA which can arise as a result of misincorporation of dUMP residues by DNA polymerase or deamination of cytosines. Therefore may reduce deleterious uracil incorporation into the viral genome, particularly in terminally differentiated cells which lack DNA repair enzymes.UniRule annotation

Catalytic activityi

Hydrolyzes single-stranded DNA or mismatched double-stranded DNA and polynucleotides, releasing free uracil.UniRule annotation
