AID expression in B-cell lymphomas causes accumulation of genomic uracil and a distinct AID mutational signature

open access: yes, 2015
The most common mutations in cancer are C to T transitions, but their origin has remained elusive. Recently, mutational signatures of APOBEC-family cytosine deaminases were identified in many common cancers, suggesting off-target deamination of cytosine ...

A unique uracil-DNA binding protein of the uracil DNA glycosylase superfamily

open access: yes, 2015
Uracil DNA glycosylases (UDGs) are an important group of DNA repair enzymes, which pioneer the base excision repair pathway by recognizing and excising uracil from DNA.

Direct measurement of the substrate preference of uracil-DNA glycosylase. [PDF]

open access: yes, 1998
Site-directed mutants of the herpes simplex virus type 1 uracil-DNA glycosylase lacking catalytic activity have been used to probe the substrate recognition of this highly conserved and ubiquitous class of DNA-repair enzyme utilizing surface plasmon ...

Phage φ29 protein p56 prevents viral DNA replication impairment caused by uracil excision activity of uracil-DNA glycosylase [PDF]

open access: yes, 2008
Protein p56 encoded by the Bacillus subtilis phage φ29 inhibits host uracil-DNA glycosylase (UDG) activity. In previous studies, we suggested that this inhibition is likely a defense mechanism developed by phage φ29 to prevent the action of UDG if ...

A uracil-DNA glycosylase inhibitor encoded by a non-uracil containing viral DNA [PDF]

open access: yes, 2006
Uracil-DNA glycosylase (UDG) is an enzyme involved in the base excision repair pathway. It specifically removes uracil from both single-stranded and double-stranded DNA. The genome of the Bacillus subtilis phage ϕ29 is a linear double-stranded DNA with a

URACIL-DNA GLYCOSYLASES PREFERENTIALLY EXCISE MISPAIRED URACIL

open access: yes, 1992
We have investigated the substrate specificity of human, viral and bacterial uracil-DNA glycosylases employing as substrate double-stranded oligonucleotides containing in the same position of the 5'-P-32-labelled strand an uracil residue facing, on the ...

Visualization of the interaction between archaeal DNA polymerase and uracil-containing DNA by atomic force microscopy

open access: yes, 2006
Deamination of cytosine to uracil is a hydrolytic reaction that is greatly accelerated at high temperatures. The resulting uracil pairs with adenine during DNA replication, thereby inducing G:C to A:T transitions in the progeny.

Uracil-Directed Ligand Tethering:  An Efficient Strategy for Uracil DNA Glycosylase (UNG) Inhibitor Development

open access: yes, 2016
Uracil DNA glycosylase (UNG) is an important DNA repair enzyme that recognizes and excises uracil bases in DNA using an extrahelical recognition mechanism.

HERPES-SIMPLEX VIRUS TYPE-1 URACIL-DNA GLYCOSYLASE - ISOLATION AND SELECTIVE-INHIBITION BY NOVEL URACIL DERIVATIVES

open access: yes, 1993
We have purified Herpes simplex type 1 (HSV1) uracil-DNA glycosylase from the nuclei of HSV1-infected HeLa cells harvested 8 h post-infection, at which time the induction of the enzyme is a maximum.
