Divalent metal ion differentially regulates the sequential nicking reactions of the GIY-YIG homing endonuclease I-BmoI. [PDF]
Homing endonucleases are site-specific DNA endonucleases that function as mobile genetic elements by introducing double-strand breaks or nicks at defined locations.

Enzymatic cleavage of type II restriction endonucleases on the 2'-O-methyl nucleotide and phosphorothioate substituted DNA. [PDF]
The effects of nucleotide analogue substitution on the cleavage efficiencies of type II restriction endonucleases have been investigated. Six restriction endonucleases (EcoRV, SpeI, XbaI, XhoI, PstI and SphI) were investigated respectively regarding ...

Selfish DNA: Homing Endonucleases Find a Home [PDF]
SummarySelf-splicing group I introns come in two flavours — those with a homing endonuclease to promote mobility of the intron, and those without an endonuclease.

New Insights Into DNA Repair Revealed by NucS Endonucleases From Hyperthermophilic Archaea
Hyperthermophilic Archaea (HA) thrive in high temperature environments and their genome is facing severe stability challenge due to the increased DNA damage levels caused by high temperature.

Nucleases are ubiquitous hydrolytic enzymes that cleave phosphodiester bond of DNA (DNases), RNA (RNases), or protein-RNA/DNA (phosphodiesterases), within the strand (endonucleases) or from the end (exonucleases) [...]

Mobile DNA elements in T4 and related phages
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.

Molecular cloning and physical mapping of murine cytomegalovirus DNA [PDF]
Murine cytomegalovirus (MCMV) Smith strain DNA is cleaved by restriction endonuclease HindIII into 16 fragments, ranging in size from 0.64 to 22.25 megadaltons.

Endonuclease activity in lipocalins [PDF]
Several lipocalins contain conserved amino acid sequences similar to the phosphodiester bond cleavage domain of sugar non-specific magnesium-dependent nucleases of the Serratia marcescens type. His-89 and Glu-127 of the S. marcescens endonuclease are believed to have a role in the active catalytic site by the attack of a water molecule at the ...

Restriction endonucleases from Bifidobacterium bifidum [PDF]
Three restriction endonucleases, BbiI, BbiII and BbiIII, have been isolated from Bifidobacterium bifidum. The recognition and cleavage specificity of BbiII was determined to be 5'-GR↓CGYC-3', identical to that of AcyI isolated from a cyanobacterium ...

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,
