Damian Mielecki et al.
PloS one, 7(1), e30588-e30588 (2012-02-01)
ALKBH proteins, the homologs of Escherichia coli AlkB dioxygenase, constitute a direct, single-protein repair system, protecting cellular DNA and RNA against the cytotoxic and mutagenic activity of alkylating agents, chemicals significantly contributing to tumor formation and used in cancer therapy....
Daria Zdżalik et al.
PloS one, 9(6), e98729-e98729 (2014-06-11)
The ALKBH family of Fe(II) and 2-oxoglutarate dependent oxygenases comprises enzymes that display sequence homology to AlkB from E. coli, a DNA repair enzyme that uses an oxidative mechanism to dealkylate methyl and etheno adducts on the nucleobases. Humans have...
Shiu-Mei Liu et al.
Journal of environmental science and health. Part A, Toxic/hazardous substances & environmental engineering, 38(6), 1099-1113 (2003-05-31)
Composition of the headspace gas affected the biotransformation pattern of toluic acid isomers in anoxic sediment slurries. Under an N2 atmosphere, o- and m-, and p-toluic acid (20-25 mg L(-1)) were biotransformed in 100 days, 77 days, and 148 days...
D Durkin et al.
Electrophoresis, 21(10), 1997-2009 (2000-07-06)
The concept of dual opposite injection in capillary electrophoresis (DOI-CE) for the simultaneous separation, under conditions of suppressed electroosmotic flow, of anionic and cationic compounds with no bias in resolution and analysis time, is extended to a higher pH range...
K H Wang et al.
Chemosphere, 40(4), 389-394 (2000-02-09)
This investigation used UV light of 365 nm and titanium dioxide in aqueous suspension to study the photocatalytic reaction of o-methylbenzoic acid under the influence of pH values, anion additives and the varieties of titanium dioxide. From experimental results, under...
Trine J Meza et al.
Nucleic acids research, 40(14), 6620-6631 (2012-04-26)
The Escherichia coli AlkB protein (EcAlkB) is a DNA repair enzyme which reverses methylation damage such as 1-methyladenine (1-meA) and 3-methylcytosine (3-meC). The mammalian AlkB homologues ALKBH2 and ALKBH3 display EcAlkB-like repair activity in vitro, but their substrate specificities are...
Erwin van den Born et al.
Nucleic acids research, 37(21), 7124-7136 (2009-09-30)
The iron(II)- and 2-oxoglutarate (2OG)-dependent dioxygenase AlkB from Escherichia coli (EcAlkB) repairs alkylation damage in DNA by direct reversal. EcAlkB substrates include methylated bases, such as 1-methyladenine (m(1)A) and 3-methylcytosine (m(3)C), as well as certain bulkier lesions, for example the...
K Watanabe et al.
Drug metabolism and disposition: the biological fate of chemicals, 23(2), 261-265 (1995-02-01)
Mouse hepatic microsomal enzymes catalyzed the oxidation of o-, m-, and p-tolualdehydes, intermediate metabolites of xylene, to the corresponding toluic acids. Cofactor requirement for the catalytic activity indicates that the microsomes contain NAD- and NADPH-dependent enzymes for this reaction. GC/MS...
Paula Esquivias et al.
Oncology reports, 31(6), 2785-2791 (2014-04-17)
Aspirin has been proposed in recent years as a candidate for chemoprevention of adenocarcinoma in patients with Barrett's esophagus. The aim of the present study was to evaluate the effect of acetylsalicylic acid (ASA) in an experimental model of esophageal...
