Protein

Uracil-DNA glycosylase

Gene

UNG1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: -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 due to deamination of cytosine. Not involved in strand-directed mismatch repair.UniRule annotation4 Publications

Miscellaneous

Present with 4820 molecules/cell in log phase SD medium.1 Publication

Catalytic activityi

Hydrolyzes single-stranded DNA or mismatched double-stranded DNA and polynucleotides, releasing free uracil.UniRule annotation1 Publication

pH dependencei

Optimum pH is 7.5-8.1 Publication
