An efficient method for DNA extraction from Cladosporioid fungi [PDF]

open access: yes, 2010
We developed an efficient method for DNA extraction from Cladosporioid fungi, which are important fungal plant pathogens. The cell wall of Cladosporioid fungi is often melanized, which makes it difficult to extract DNA from their cells.

Alleviation of restriction by DNA condensation and non-specific DNA binding ligands [PDF]

open access: yes, 2004
During conditions of cell stress, the type I restriction and modification enzymes of bacteria show reduced, but not zero, levels of restriction of unmethylated foreign DNA.

Fingerprinting of Bacterial Genomes by Amplification of DNA Fragments Surrounding Rare Restriction Sites

open access: yesBioTechniques, 2001
A method for generating limited representations of total bacterial DNA, without prior knowledge of the DNA sequence, has been developed. This method consists of three steps: digestion with two restriction enzymes, ligation of two oligonucleotide adapters

Restriction enzyme mapping of vaccinia virus DNA [PDF]

open access: yesJournal of Virology, 1982
The cleavage sites for the restriction enzymes Bg/I, HindIII, KpnI, SalI, SmaI, and XhoI were located, from primary data, on the DNA isolated from the WR strain of vaccinia virus. Bg/I and SmaI divide the DNA into five segments which can be isolated by sucrose gradient centrifugation.

Enhancement of PCRs by Partial Restriction Digestion of Genomic Templates

open access: yesBioTechniques, 1999
Genomic DNA preparations derived from mammalian cells can often exhibit poor template activity in PCR, particularly when carried out on target sequences present at low copy number. Using genomic DNA bearing SV40 sequences integrated into host chromosomal

NEBcutter: a program to cleave DNA with restriction enzymes [PDF]

open access: yesNucleic Acids Research, 2003
NEBcutter, version 1.0, is a program available via a web server (http://tools.neb.com/NEBcutter) that will accept an input DNA sequence and produce a comprehensive report of the restriction enzymes that will cleave the sequence. It produces a variety of outputs including restriction enzyme maps, theoretical digests and links into the restriction enzyme

REBASE--enzymes and genes for DNA restriction and modification [PDF]

open access: yesNucleic Acids Research, 2007
REBASE is a comprehensive database of information about restriction enzymes, DNA methyltransferases and related proteins involved in the biological process of restriction-modification. It contains fully referenced information about recognition and cleavage sites, isoschizomers, neoschizomers, commercial availability, methylation sensitivity, crystal ...

Re-evaluating the kinetics of ATP hydrolysis during initiation of DNA sliding by Type III restriction enzymes [PDF]

open access: yes, 2015
DNA cleavage by the Type III restriction enzymes requires long-range protein communication between recognition sites facilitated by thermally-driven 1D diffusion. This ‘DNA sliding’ is initiated by hydrolysis of multiple ATPs catalysed by a helicase-like

Internuclear gene silencing in Phytophthora infestans is established through chromatin remodelling [PDF]

open access: yes, 2008
In the plant pathogen Phytophthora infestans, nuclear integration of inf1 transgenic DNA sequences results in internuclear gene silencing of inf1. Although silencing is regulated at the transcriptional level, it also affects transcription from other ...

Straightforward Procedure for Laboratory Production of DNA Ladder

open access: yesJournal of Nucleic Acids, 2012
DNA ladder is commonly used to determine the size of DNA fragments by electrophoresis in routine molecular biology laboratories. In this study, we report a new procedure to prepare a DNA ladder that consists of 10 fragments from 100 to 1000 bp.
