Functional Traits Co-Occurring with Mobile Genetic Elements in the Microbiome of the Atacama Desert [PDF]

open access: yes, 2019
Mobile genetic elements (MGEs) play an essential role in bacterial adaptation and evolution. These elements are enriched within bacterial communities from extreme environments. However, very little is known if specific genes co-occur with MGEs in extreme

ATP hydrolysis by the SNF2 domain of the ultraspecific maintenance methylase Dnmt5 drives recognition and modification of hemimethylated DNA [PDF]

open access: yes, 2020
SUMMARYC. neoformansDnmt5 is an ultraspecific maintenance-type CpG methyltransferase (DNMT) that mediates long-term epigenome evolution. It harbors a DNMT domain and SNF2 ATPase domain. We find that the SNF2 domain couples substrate specificity to an ATPase step that is essential for DNA methylation.

Infection with a Virulent Strain of Wolbachia Disrupts Genome Wide-Patterns of Cytosine Methylation in the Mosquito Aedes aegypti [PDF]

open access: yes, 2015
BACKGROUND Cytosine methylation is one of several reversible epigenetic modifications of DNA that allow a greater flexibility in the relationship between genotype and phenotype.

Introduction and expression of the bacterial PaeR7 methylase gene in mammalian cells [PDF]

open access: yes, 1986
An approach is devised for studying the role of DNA methylation in eukaryotic gene expression. The approach is based on the expression of site-specific bacterial methylase genes in animal cells.

Purification and characterization of the MspI DNA methyltransferase cloned and overexpressed in E. coli [PDF]

open access: yes, 1992
The MspI restriction-modification system, which recognizes the sequence 5'-CCGG-3', has been previously cloned and sequenced (1). We subcloned the methyltransferase gene (M.MspI) downstream of the ptac promoter in the multicopy vector pUC119 and ...

The HgaI restriction-modification system contains two cytosine methylase genes responsible for modification of different DNA strands

open access: yesJournal of Biological Chemistry, 1991
A DNA fragment of about 3.4 kilobase pairs that expressed the HgaI modification activity was cloned from the chromosomal DNA of Haemophilus gallinarum, and its nucleotide sequence was determined. Two open reading frames (ORF) which could code for structurally similar proteins were identified in the upstream and middle regions and a truncated ORF in the

Cloning and characterization of the genes encoding the MspI restriction modification system [PDF]

open access: yes, 1989
The genes encoding the MspI restriction modification system, which recognizes the sequence 5' CCGG, have been cloned into pUC9. Selection was based on expression of the cloned methylase gene which renders plasmid DNA insensitive to MspI cleavage in vitro.

The enzymes LSD1 and Set1A cooperate with the viral protein HBx to establish an active hepatitis B viral chromatin state [PDF]

open access: yes, 2016
Indexación: Web of ScienceWith about 350 million people chronically infected around the world hepatitis B is a major health problem. Template for progeny HBV synthesis is the viral genome, organized as a minichromosome (cccDNA) inside the hepatocyte ...

NF-κB: Regulation by Methylation [PDF]

open access: yes, 2015
In normal cells exposed to stress, the central transcription factor NF-κB is activated only transiently, to modulate the activation of downstream immune responses.
