Watanabe T, Nunoshiba T, Kawata M, Yamamoto K
Biochem Biophys Res Commun
. 2001 May;
284(1):179-84.
PMID: 11374888
Base substitution mutations are not distributed randomly in that most are located at a few specific hotspots sites. We have been studying 7,8-dihydro-8-oxoguanine mutagenesis in Escherichia coli in the supF...

Mol Gen Genet
. 2001 Mar;
264(6):836-41.
PMID: 11254131
We examined whether strand identity with respect to DNA replication influences strand bias for 8-oxo-7,8-dihydroguanine (8-oxoG) mutagenesis. The specificity of 8-oxoG mutagenesis was determined in a mutM mutY or a...

Proc Natl Acad Sci U S A
. 2000 Dec;
97(26):14257-62.
PMID: 11121031
The complete genomic sequence of the archaeon Thermoplasma volcanium, possessing optimum growth temperature (OGT) of 60 degrees C, is reported. By systematically comparing this genomic sequence with the other known...

Biochem Biophys Res Commun
. 2000 Dec;
279(2):427-32.
PMID: 11118303
Escherichia coli K-12 strain EY5, deficient in oxyR, was constructed to assess the role of oxyR and oxyR-regulated regulon in spontaneous mutagenesis. Mutagenesis was monitored by selecting two forward mutations...

J Biol Chem
. 1999 Nov;
274(49):34832-7.
PMID: 10574955
We measured the generation of hydroxyl radical (OH(.)) and oxidative DNA lesions in aerobically grown Escherichia coli cells lacking in both superoxide dismutases (SodA SodB) and repressor of iron uptake...

Mutat Res
. 1999 Jun;
442(1):1-8.
PMID: 10366767
The reduced form of glutathione (GSH) is a well-known antioxidant, while there have been few reports indicating the contribution of glutathione to protection of Escherichia coli cells from the lethal...

Mutagenesis
. 1999 May;
14(2):249-53.
PMID: 10229930
The spectrum of mutations induced by cobalt(II) chloride (CoCl2) was examined using plasmid pUB3 DNA, which was propagated after transfection into Escherichia coli SY1032/pKY241 host cells. The vector plasmid carried...

J Radiat Res
. 1999 Apr;
39(4):263-70.
PMID: 10196781
An improved system to examine forward mutations that occurred in the supF gene of Escherichia coli carried on a multicopy plasmid is described. The system was validated by measuring spontaneous...

Crit Rev Eukaryot Gene Expr
. 1996 Jan;
6(4):377-89.
PMID: 8959373
All organisms have adapted to environmental changes by acquiring various functions controlled by gene regulation. In bacteria, a number of specific responses have been found to confer cell survival in...

PMID: 7532626
Nitric oxide (NO.) is produced as a cytotoxic free radical through enzymatic oxidation of L-arginine in activated macrophages. Pure NO. gas was previously found to induce the Escherichia coli soxRS...
