Thymine DNA Glycosylase Is Essential for Active DNA Demethylation by Linked Deamination-Base Excision Repair

S Cortellino, J Xu, M Sannai, R Moore, E Caretti… - Cell, 2011 - Elsevier
DNA methylation is a major epigenetic mechanism for gene silencing. Whereas methyltransferases
mediate cytosine methylation, it is less clear how unmethylated regions in mammalian genomes
are protected from de novo methylation and whether an active demethylating activity is ...

The edited transcriptome: novel high throughput approaches to detect nucleotide deamination

G Silberberg… - Current Opinion in Genetics & Development, 2011 - Elsevier
RNA editing is emerging as a wide-spread phenomenon both in coding and non-coding RNA
regions. While the mechanisms underlying many of these post-transcriptional modifications have
not been elucidated, RNA editing by nucleotide deamination has been known for over ...

Enzymatic Deamination of the Epigenetic Base N-6-Methyladenine

[PDF] from salilab.orgSS Kamat, H Fan, JM Sauder… - Journal of the …, 2011 - ACS Publications
Two enzymes of unknown function from the amidohydrolase superfamily were discovered to
catalyze the deamination of N-6-methyladenine to hypoxanthine and methyl amine. The methylation
of adenine in bacterial DNA is a common modification for the protection of host DNA ...

Oxidation and Deamination of DNA by Endogenous Sources

PC Dedon - Chemical Carcinogenesis, 2011 - Springer
Abstract DNA damage represents one of the fundamental mechanistic features of chemical
carcinogenesis, with damage chemistry falling into three general cat- egories: oxidation,
deamination, and alkylation. This chapter addresses the basic biological chemistry of ...

Deamination role of inducible glutamate dehydrogenase isoenzyme 7 in Brassica napus leaf protoplasts

M Watanabe, O Yumi, Y Itoh, K Yasuda, K Kamachi… - Phytochemistry, 2011 - Elsevier
Glutamate dehydrogenase (GDH) is a ubiquitous enzyme that catalyzes the reversible amination
of 2-oxoglutarate to glutamate. In Brassica napus, GDH isoenzymes 1 and 7 are hexamers of
β and α subunits, respectively and the isoenzyme profile in leaves is known to change on ...
