Cloning DNA Fragments Between Two Adjacent/Overlapping Restriction Sites Using a “Positive Stuffer”

open access: yesBioTechniques, 1997
Here we describe a solution to a common problem encountered in recombinant DNA cloning when directional cloning of a DNA fragment into a predetermined plasmid requires the use of restriction enzymes with adjacent or overlapping recognition sites.

Comparative analysis of 18S rRNA genes from Myxobolus aeglefini Auerbach, 1906 isolated from cod (Gadus morhua), Plaice (Pleuronectes platessa) and dab (Limanda limanda), using PCR-RFLP [PDF]

open access: yes, 2002
The myxosporean parasite Myxobolus aeglefini is a marine species, which can be found in the cartilage of mainly gadid fish species. The parasite has, however, been recorded in the flatfish plaice (Pleuronectes platessa) and dab (Limanda limanda).

A nomenclature for restriction enzymes, DNA methyltransferases, homing endonucleases and their genes [PDF]

open access: yesNucleic Acids Research, 2003
A nomenclature is described for restriction endonucleases, DNA methyltransferases, homing endonucleases and related genes and gene products. It provides explicit categories for the many different Type II enzymes now identified and provides a system for naming the putative genes found by sequence analysis of microbial genomes.

The nicotinamide hypothesis revisited—plant defense signaling integrating PARP, nicotinamide, nicotinic acid, epigenetics, and glutathione

open access: yesFEBS Letters, EarlyView.
Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...

Genetic Analysis Using Partial Sequencing of Melanocortin 4 Receptor (MC4R) Gene in Bligon Goat

open access: yesMedia Peternakan, 2017
Melanocortin 4 Receptor gene is involved in sympathetic nerve activity, adrenal and thyroid functions, and media for leptin in regulating energy balance and homeostasis. The aim of this research was to perform genetic analysis of MC4R gene sequences from

The Epigenomic Landscape of Prokaryotes. [PDF]

open access: yesPLoS Genetics, 2016
DNA methylation acts in concert with restriction enzymes to protect the integrity of prokaryotic genomes. Studies in a limited number of organisms suggest that methylation also contributes to prokaryotic genome regulation, but the prevalence and ...

DNA restriction enzyme analysis of bovine adenoviruses.

open access: yesIntervirology, 1988
Eight reference strains of the nine accepted bovine adenovirus serotypes were compared by means of restriction enzyme (RE) analysis of the viral DNA. The study was carried out with the aim to identify RE giving restriction patterns which are particularly feasible for identification of new isolates and useful for their classification into subgroups. The

A working model for cytoplasmic assembly of H/ACA snoRNPs

open access: yesFEBS Letters, EarlyView.
Dyskerin is the component of nuclear H/ACA ribonucleoproteins (RNPs) endowed with pseudouridine synthase catalytic activity. Two isoforms of human dyskerin have been characterized: the abundant Iso1, mainly nuclear, and the shorter Iso3, mainly cytoplasmic but occasionally imported into nuclei.

Restriction enzymes use a 24 dimensional coding space to recognize 6 base long DNA sequences.

open access: yesPLoS ONE, 2019
Restriction enzymes recognize and bind to specific sequences on invading bacteriophage DNA. Like a key in a lock, these proteins require many contacts to specify the correct DNA sequence.

Restriction enzyme body doubles and PCR cloning: on the general use of type IIs restriction enzymes for cloning. [PDF]

open access: yesPLoS ONE, 2014
The procedure described here allows the cloning of PCR fragments containing a recognition site of the restriction endonuclease (Type IIP) used for cloning in the sequence of the insert.
