Interactions of Dnd Proteins involved in bacterial DNA phosphorothioate modification

open access: yesFrontiers in Microbiology, 2015
DNA phosphorothioation (PT) is the first discovered physiological DNA backbone modification, in which a non-bridging oxygen atom of the phosphodiester bond is replaced with a sulfur atom in Rp (Rectus for plane) configuration. PT modification is governed

Atomic force microscopy of the EcoKI Type I DNA restriction enzyme bound to DNA shows enzyme dimerization and DNA looping [PDF]

open access: yes, 2009
Atomic force microscopy (AFM) allows the study of single protein–DNA interactions such as those observed with the Type I Restriction–Modification systems.

Adapterama III: Quadruple-indexed, double/triple-enzyme RADseq libraries (2RAD/3RAD) [PDF]

open access: yesPeerJ, 2019
Molecular ecologists frequently use genome reduction strategies that rely upon restriction enzyme digestion of genomic DNA to sample consistent portions of the genome from many individuals (e.g., RADseq, GBS). However, researchers often find the existing

The Emerging Role of Ten-Eleven Translocation 1 in Epigenetic Responses to Environmental Exposures. [PDF]

open access: yes, 2020
Mounting evidence from epidemiological studies and animal models has linked exposures to environmental factors to changes in epigenetic markers, especially in DNA methylation.

Expression of functional recombinant human tissue transglutaminase (TG2) using the bac-to-bac baculovirus expression system [PDF]

open access: yes, 2016
Purpose: Tissue transglutaminase (TG2) is a unique multifunctional enzyme. The enzyme possesses enzymatic activities such as transamidation/crosslinking and non-enzymatic functions such as cell migration and signal transduction.

Plasmodium falciparum gametogenesis essential protein 1 (GEP1) is a transmission‐blocking target

open access: yesFEBS Letters, EarlyView.
This study shows Plasmodium falciparum GEP1 is vital for activating sexual stages of malarial parasites even independently of a mosquito factor. Knockout parasites completely fail gamete formation even when a phosphodiesterase inhibitor is added. Two single‐nucleotide polymorphisms (V241L and S263P) are found in 12%–20% of field samples.

On the DNA cleavage mechanism of Type I restriction enzymes [PDF]

open access: yes, 2017
Although the DNA cleavage mechanism of Type I restriction-modification enzymes has been extensively studied, the mode of cleavage remains elusive. In this work, DNA ends produced by EcoKI, EcoAI and EcoR124I, members of the Type IA, IB and IC families ...

4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase in malaria parasites and enhances atovaquone efficacy

open access: yesFEBS Letters, EarlyView.
Atovaquone is an antimalarial requiring potentiation for sufficient efficacy. We pursued strategies to enhance its activity, showing that 4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase, decreasing ubiquinone biosynthesis. Since atovaquone competes with ubiquinol in mitochondria, 4‐nitrobenzoate facilitates its action, potentiating ...

A versatile platform for single-molecule enzymology of restriction endonuclease [PDF]

open access: yesJournal of Innovative Optical Health Sciences, 2019
Enzymes are the major players for many biological processes. Fundamental studies of the enzymatic activity at the single-molecule level provides important information that is otherwise inaccessible at the ensemble level.
