Suppression of APOBEC3-mediated restriction of HIV-1 by Vif

open access: yesFrontiers in Microbiology, 2014
The APOBEC3 restriction factors are a family of deoxycytidine deaminases that are able to suppress replication of viruses with a single-stranded DNA intermediate by inducing mutagenesis and functional inactivation of the virus.

The Hyperthermophilic Restriction-Modification Systems of Thermococcus kodakarensis Protect Genome Integrity

open access: yesFrontiers in Microbiology, 2021
Thermococcus kodakarensis (T. kodakarensis), a hyperthermophilic, genetically accessible model archaeon, encodes two putative restriction modification (R-M) defense systems, TkoI and TkoII.

Microarray-Based Analysis of Methylation Status of CpGs in Placental DNA and Maternal Blood DNA--Potential New Epigenetic Biomarkers for Cell Free Fetal DNA-Based Diagnosis. [PDF]

open access: yesPLoS ONE, 2015
Epigenetic markers for cell free fetal DNA in the maternal blood circulation are highly interesting in the field of non-invasive prenatal testing since such markers will offer a possibility to quantify the amount of fetal DNA derived from different ...

EcoRV catalysis with a pre-bent substrate

open access: yesAIP Advances, 2015
Enzymes are deformable molecules which often adapt their conformation to the substrate’s geometry. In the case of restriction enzymes acting on DNA, the substrate (DNA) is deformable also.

Restriction Enzyme Analysis of Tomato Chloroplast and Chromoplast DNA [PDF]

open access: yesPlant Physiology, 1986
Plastid DNA was isolated from the chloroplasts of tomato (Lycopersicon esculentum var Traveler 76) leaves and the chromoplasts of ripe tomato fruit. Comparisons of the two DNAs were made by restriction endonuclease analysis using PvuII, HpaI, and Bg1I.

Structural and functional analysis of the symmetrical Type I restriction endonuclease R.EcoR124I<sub>NT</sub>

open access: yesPLoS ONE, 2012
Type I restriction-modification (RM) systems are comprised of two multi-subunit enzymes, the methyltransferase (∼160 kDa), responsible for methylation of DNA, and the restriction endonuclease (∼400 kDa), responsible for DNA cleavage. Both enzymes share a

REHUNT: a reliable and open source package for restriction enzyme hunting

open access: yesBMC Bioinformatics, 2018
Background Restriction enzymes are used frequently in biotechnology. However, manual mining of restriction enzymes is challenging. Furthermore, integrating available restriction enzymes into different bioinformatics systems is necessary for many ...
