Conflicts Targeting Epigenetic Systems and Their Resolution by Cell Death: Novel Concepts for Methyl-Specific and Other Restriction Systems [PDF]

Epigenetic modification of genomic DNA by methylation is important for defining the epigenome and the transcriptome in eukaryotes as well as in prokaryotes.

Type I restriction endonucleases are true catalytic enzymes [PDF]

, 2009
Type I restriction endonucleases are intriguing, multifunctional complexes that restrict DNA randomly, at sites distant from the target sequence. Restriction at distant sites is facilitated by ATP hydrolysis-dependent, translocation of double-stranded ...

Unraveling Mycobacterium tuberculosis acid resistance and pH homeostasis mechanisms

FEBS Letters, EarlyView.
Mycobacterium tuberculosis exhibits a remarkable resilience to acid stress. In this Review, we discuss some of the molecular mechanisms and metabolic pathways used by the tubercle bacilli to adapt and resist host‐mediated acid stress. Mycobacterium tuberculosis (Mtb) is a successful pathogen that has developed a variety of strategies to survive and ...

Enzymatic Digestion Pattern of Varicella Zoster Virus ORF38 and ORF54 in Chickenpox Patients Using RFLP Technique [PDF]

Iranian Journal of Pathology, 2016
Background: Varicella zoster virus (VZV) causes chickenpox in children and zoster (zona) in the elderly. Using RFLP-PCR method for detection of VZV specific SNPs ORF38, 54 and 62 could  distinguish the profile of VZV isolates.

DNA Methylation Tools and Strategies: Methods in a Review

Asian Pacific Journal of Cancer Biology, 2019
DNA methylation is known as an important epigenetic change in plants and vertebrates genome. In this process, the methyl group transferred by DNA methyl transferase enzymes to cytosine at carbon residue 5 often in the CpG dinucleotide context.

Hepatitis B virus genotype assignment using restriction fragment length polymorphism patterns [PDF]

, 1933
Hepatitis B virus (HBV) is classified into genotypes A–F, which is important for clinical and etiological investigations. To establish a simple genotyping method, 68 full-genomic sequences and 106 S gene sequences were analyzed by the molecular ...

Enzyme-free cloning: a rapid method to clone PCR products independent of vector restriction enzyme sites.

Nucleic Acids Research, 1999
We describe a simple method for the cloning of PCR products without the need for post-amplification enzymatic treatment. Tailed PCR primer sets are used to create complementary staggered overhangs on both insert and vector by a post-PCR denaturation ...

Unconventional mRNA processing and degradation pathways for the polycistronic yrzI (spyTA) mRNA in Bacillus subtilis

FEBS Letters, EarlyView.
The S1025 peptide is the major antidote to the YrzI toxin, which we renamed here as SpyT (Small Peptide YrzI Toxin) and SpyA (Small Peptide YrzI Antitoxin) (1). Degradation of the toxin–antitoxin spyTA mRNA, either by a translation‐dependent cleavage by the endoribonuclease Rae1 (2) or by direct attack by 3′‐exoribonucleases (3), also contributes to ...
