Single Stranded DNA Translocases can Push Single Stranded DNA Binding Proteins along Single Stranded DNA [PDF]

open access: yesBiophysical Journal, 2016
Single-stranded (ss) DNA binding proteins (SSBs) protect ssDNA intermediates during genome maintenance. These SSBs must eventually be displaced or reorganized and one potential mechanism for reorganization is pushing of the SSB along the DNA by ssDNA translocases (ATP-dependent motors).

UPF1 promotes the formation of R loops to stimulate DNA double-strand break repair

open access: yesNature Communications, 2021
R loops are formed when single-stranded RNA anneals to one strand of DNA, forming three-stranded structures containing DNA-RNA hybrids and the displaced non-template single-stranded DNA. Here the authors reveal that the DNA:RNA helicase UPF1 plays a role

RPA shields inherited DNA lesions for post-mitotic DNA synthesis

open access: yesNature Communications, 2021
Single-stranded DNA during DNA replication and repair in S/G2 needs protection by replication protein A (RPA). Here the authors reveal that RPA also shields inherited single-stranded DNA in G1, representing replication remnants from the previous cell ...

Capture and analysis of double‐stranded DNA with the α‐hemolysin nanopore: Fundamentals and applications

open access: yesElectrochemical Science Advances, 2022
The α‐hemolysin nanopore has attracted much attention as a tool for the single‐molecule analysis of DNA due to its potential as an ultra‐sensitive, specific, and label‐free sensing technique. The vast majority of DNA sensing research with the α‐hemolysin

Cooperativity-Dependent Folding of Single-Stranded DNA

open access: yesPhysical Review X, 2021
The folding of biological macromolecules is a fundamental process of which we lack a full comprehension. Mostly studied in proteins and RNA, single-stranded DNA (ssDNA) also folds, at physiological salt conditions, by forming nonspecific secondary ...

Continuous Approximation for Interaction Energy Transfer of DNA through Lipid Bilayers

open access: yesDiscrete Dynamics in Nature and Society, 2018
In this study the interaction energies for single-stranded DNA and double-stranded DNA molecules with a lipid bilayer are investigated. The 6-12 Lennard-Jones potential and continuous approximation are used to derive analytical expressions for these ...

The Characteristics of New SSB Proteins from Metagenomic Libraries and Their Use in Biotech Applications

open access: yesProceedings, 2020
Single-stranded DNA binding proteins (SSBs) bind to single-stranded DNA in a sequence-independent manner to prevent formation of secondary structures and protect DNA from nuclease degradation.

Separation of Short Single- and Double-Stranded DNA Based on Their Adsorption Kinetics Difference on Graphene Oxide

open access: yesNanomaterials, 2013
Separation of short single- and double-stranded DNA typically requires gel electrophoresis followed by DNA extraction, which is a time consuming process.

Genetic and biochemical identification of a novel single-stranded DNA binding complex in Haloferax volcanii

open access: yesFrontiers in Microbiology, 2012
Single-stranded DNA binding proteins play an essential role in DNA replication and repair. They use oligosaccharide-binding folds, a five-stranded ß-sheet coiled into a closed barrel, to bind to single-stranded DNA thereby protecting and stabilizing
