Site-specific restriction endonucleases in cyanobacteria [PDF]

open access: yesJournal of Applied Microbiology, 2000
Planktic cyanobacteria were screened for endodeoxyribonucleases. Principal component analysis (PCA) was employed to demonstrate a potential relationship between certain enzymes and a group of cyanobacteria. The data were obtained from a data bank and this study.Enzymes were partially purified using column chromatography.

Sequence organization of feline leukemis virus DNA in infected cells [PDF]

open access: yes, 1980
A restriction site map has been deduced of unintegrated and integrated FeLV viral DNA found in human RD cells after experimental infection with the Gardner-Arnstein strain of FeLV.

Special features of RAD Sequencing data:implications for genotyping [PDF]

open access: yes, 2012
Restriction site-associated DNA Sequencing (RAD-Seq) is an economical and efficient method for SNP discovery and genotyping. As with other sequencing-by-synthesis methods, RAD-Seq produces stochastic count data and requires sensitive analysis to develop ...

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.

Broadness and specificity: ArdB, ArdA, and Ocr against various restriction-modification systems

open access: yesFrontiers in Microbiology, 2023
ArdB, ArdA, and Ocr proteins inhibit the endonuclease activity of the type I restriction-modification enzymes (RMI). In this study, we evaluated the ability of ArdB, ArdA, and Ocr to inhibit different subtypes of Escherichia coli RMI systems (IA, IB, and

Differentiation between Aspergillus flavus and Aspergillus parasiticus from Pure Culture and Aflatoxin-Contaminated Grapes Using PCR-RFLP Analysis of aflR-aflJ Intergenic Spacer [PDF]

open access: yes, 2011
Aflatoxins (AFs) represent the most important single mycotoxin-related food safety problem in developed and developing countries as they have adverse effects on human and animal health. They are produced mainly by Aspergillus flavus and A.

Avoidance of recognition sites of restriction-modification systems is a widespread but not universal anti-restriction strategy of prokaryotic viruses

open access: yesBMC Genomics, 2018
Background Restriction-modification (R-M) systems protect bacteria and archaea from attacks by bacteriophages and archaeal viruses. An R-M system specifically recognizes short sites in foreign DNA and cleaves it, while such sites in the host DNA are ...

Development of a molecular method for the rapid screening and identification of the three functionally relevant polymorphisms in the human TAS2R38 receptor gene in studies of sensitivity to the bitter taste of PROP [PDF]

open access: yes, 2015
The objective of this work was to develop a rapid screening method to identify the three single nucleotide polymorphisms (SNPs) in the TAS2R38 gene, with the aim of providing a significant contribution to studies designed to assess sensitivity to the ...
