A novel role for Escherichia coli endonuclease VIII in prevention of spontaneous G-->T transversions
Blaisdell J, Hatahet Z, Wallace S
J Bacteriol
. 1999 Oct;
181(20):6396-402.
PMID: 10515930
In the bacterium Escherichia coli, oxidized pyrimidines are removed by two DNA glycosylases, endonuclease III and endonuclease VIII (endo VIII), encoded by the nth and nei genes, respectively. Double mutants...

Harrison L, Hatahet Z, Wallace S
J Mol Biol
. 1999 Jul;
290(3):667-84.
PMID: 10395822
When ionizing radiation traverses a DNA molecule, a combination of two or more base damages, sites of base loss or single strand breaks can be produced within 1-4 nm on...

Hatahet Z, Zhou M, Ide H, Morrical S, Wallace S
J Mol Biol
. 1999 Feb;
286(4):1045-57.
PMID: 10047481
The influence of sequence context on the ability of DNA polymerase to bypass sites of base loss was addressed using an in vitro selection system. Oligonucleotides containing either an aldehydic...

Hatahet Z, Zhou M, Morrical S, Wallace S
Proc Natl Acad Sci U S A
. 1998 Jul;
95(15):8556-61.
PMID: 9671716
In vitro selection was used to define sequence contexts that significantly enhanced the mutagenic potential of 7, 8-dihydro-8-oxoguanine (8-oxoG). Contexts that simultaneously reduced the efficiency of 8-oxoG cleavage by formamidopyrimidine...

Purmal A, Lampman G, Bond J, Hatahet Z, Wallace S
J Biol Chem
. 1998 May;
273(16):10026-35.
PMID: 9545349
A major stable oxidation product of DNA cytosine is uracil glycol (Ug). Because of the potential of Ug to be a strong premutagenic lesion, it is important to assess whether...

Harrison L, Hatahet Z, Purmal A, Wallace S
Nucleic Acids Res
. 1998 Mar;
26(4):932-41.
PMID: 9461450
Bursts of free radicals produced by ionization of water in close vicinity to DNA can produce clusters of opposed DNA lesions and these are termed multiply damaged sites (MDS). How...

Fung H, Kow Y, Van Houten B, Taatjes D, Hatahet Z, Janssen Y, et al.
Cancer Res
. 1998 Jan;
58(2):189-94.
PMID: 9443389
Only two DNA repair enzymes, DNA polymerase beta and O6-methylguanine-DNA methyltransferase, have been shown to be inducible in mammalian cells by genotoxic agents. We show here that crocidolite asbestos induces...

Jiang D, Hatahet Z, Melamede R, Kow Y, Wallace S
J Biol Chem
. 1998 Jan;
272(51):32230-9.
PMID: 9405426
Escherichia coli endonuclease VIII (endo VIII) was identified as an enzyme that, like endonuclease III (endo III), removes radiolysis products of thymine including thymine glycol, dihydrothymine, beta-ureidoisobutyric acid, and urea...

Jiang D, Hatahet Z, Blaisdell J, Melamede R, Wallace S
J Bacteriol
. 1997 Jun;
179(11):3773-82.
PMID: 9171429
Escherichia coli possesses two DNA glycosylase/apurinic lyase activities with overlapping substrate specificities, endonuclease III and endonuclease VIII, that recognize and remove oxidized pyrimidines from DNA. Endonuclease III is encoded by...

Moutafis M, Hatahet Z, Castelain M, Renaudin M, Monnot A, Fischler M
Intensive Care Med
. 1995 Jun;
21(6):537-41.
PMID: 7560498
Monitoring of nitric oxide (NO) and nitrogen dioxide (NO2) is a prerequisite for the clinical use of NO. Chemiluminescence, the reference method, cannot be used as a routine in clinical...
