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.

Flap Endonuclease 1 [PDF]

open access: yesAnnual Review of Biochemistry, 2013
First discovered as a structure-specific endonuclease that evolved to cut at the base of single-stranded flaps, flap endonuclease (FEN1) is now recognized as a central component of cellular DNA metabolism. Substrate specificity allows FEN1 to process intermediates of Okazaki fragment maturation, long-patch base excision repair, telomere maintenance ...

Broken Symmetry in Homing Endonucleases [PDF]

open access: yes, 2006
Homing DNA endonucleases are highly site-specific enzymes that initiate the transfer of mobile DNA elements. In this issue of Structure, Spiegel et al.

Selfish DNA: New Abode for Homing Endonucleases [PDF]

open access: yes, 2002
A 30-year old conundrum concerning the genetics of T-even bacteriophages has at last been solved, the answer turning out to involve free-standing homologs of intron-encoded homing ...

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.

Computational approaches to restriction endonucleases

open access: yes, 2003
Type II restriction endonucleases catalyze phosphodiester bond hydrolysis in bacteria to protect the host cell from invading phage DNA. Due to their exquisite sequence selectivity type II restriction endonucleases serve as excellent model systems for ...
