Activity of Vsr endonucleases encoded by Neisseria gonorrhoeae FA1090 is influenced by MutL and MutS proteins

open access: yesBMC Microbiology, 2018
Background The functioning of DNA repair systems is based on correct interactions between proteins involved in DNA repair. Very Short Patch (VSP) repair is a DNA repair system that corrects mismatches resulting from the deamination of 5-methylcytosine ...

Mobile DNA elements in T4 and related phages

open access: yesVirology Journal, 2010
Mobile genetic elements are common inhabitants of virtually every genome where they can exert profound influences on genome structure and function in addition to promoting their own spread within and between genomes.

CiAPEX2 and CiP0, candidates of AP endonucleases in Ciona intestinalis, have 3′-5′ exonuclease activity and contribute to protection against oxidative stress

open access: yesGenes and Environment, 2017
Apurinic/apyrimidinic (AP) sites are one of the most frequent DNA lesions. AP sites inhibit transcription and DNA replication, and induce cell death. AP endonucleases are key enzymes in AP site repair. Several types of AP endonucleases have been reported,

Engineering Infrequent DNA Nicking Endonuclease by Fusion of a BamHI Cleavage-Deficient Mutant and a DNA Nicking Domain

open access: yesFrontiers in Microbiology, 2022
Strand-specific DNA nicking endonucleases (NEases) typically nick 3–7 bp sites. Our goal is to engineer infrequent NEase with a >8 bp recognition sequence.

Two restriction endonucleases [PDF]

open access: yesBiochemistry and Molecular Biology Education, 2006
AbstractTerms to be familiar with before you start to solve the test: restriction endonucleases; palindromic sequences; blunt ends; cohesive (“sticky”) ends; in vitro DNA synthesis; radioactive nucleotide precursors; template‐primer complexes; DNA ligation.

Sequence-specific DNA nicking endonucleases

open access: yesBiomolecular Concepts, 2015
A group of small HNH nicking endonucleases (NEases) was discovered recently from phage or prophage genomes that nick double-stranded DNA sites ranging from 3 to 5 bp in the presence of Mg2+ or Mn2+.

Structure-Specific Endonucleases in DNA Repair

open access: yesCHIMIA, 2009
Nucleotide excision repair (NER) is an essential DNA repair pathway that addresses a variety of DNA lesions formed by UV light, environmental mutagens and agents used in cancer chemotherapy.

F-CphI represents a new homing endonuclease family using the Endo VII catalytic motif

open access: yesMobile DNA, 2018
Background There are six known families of homing endonucleases, LAGLIDADG, GIY-YIG, HNH, His-Cys box, PD-(D/E)-XK, and EDxHD, which are characterized by their conserved residues.

Protein Domain Guided Screen for Sequence Specific and Phosphorothioate-Dependent Restriction Endonucleases

open access: yesFrontiers in Microbiology, 2020
Modification dependent restriction endonucleases (MDREs) restrict modified DNA, typically with limited sequence specificity (∼2–4 bp). Here, we focus on MDREs that have an SRA and/or SBD (sulfur binding domain) fused to an HNH endonuclease domain ...

SLX4 Assembles a Telomere Maintenance Toolkit by Bridging Multiple Endonucleases with Telomeres

open access: yesCell Reports, 2013
SLX4 interacts with several endonucleases to resolve structural barriers in DNA metabolism. SLX4 also interacts with telomeric protein TRF2 in human cells. The molecular mechanism of these interactions at telomeres remains unknown.
