Restriction modification systems in archaea: A panoramic outlook
Restriction modification (RM) systems are one of the ubiquitous yet primitive defense responses employed by bacteria and archaea with the primary role of safeguarding themselves against invading bacteriophages.

Restriction enzymes use a 24 dimensional coding space to recognize 6 base long DNA sequences.
Restriction enzymes recognize and bind to specific sequences on invading bacteriophage DNA. Like a key in a lock, these proteins require many contacts to specify the correct DNA sequence.

The Epigenomic Landscape of Prokaryotes. [PDF]
DNA methylation acts in concert with restriction enzymes to protect the integrity of prokaryotic genomes. Studies in a limited number of organisms suggest that methylation also contributes to prokaryotic genome regulation, but the prevalence and ...

Restriction and modification of deoxyarchaeosine (dG+)-containing phage 9 g DNA
E. coli phage 9 g contains the modified base deoxyarchaeosine (dG+) in its genome. The phage encodes its own primase, DNA ligase, DNA polymerase, and enzymes necessary to synthesize and incorporate dG+.

Restriction enzyme body doubles and PCR cloning: on the general use of type IIs restriction enzymes for cloning. [PDF]
The procedure described here allows the cloning of PCR fragments containing a recognition site of the restriction endonuclease (Type IIP) used for cloning in the sequence of the insert.

Investigation of DNA-protein Sequence-Specific Interactions with a ds-DNA Array
The sequence specific recognitions between DNAs and proteins play important roles in many biological functions. The use of double-stranded DNA arrays (ds-DNA arrays) for studying sequence specific recognition between DNAs and proteins is a promising ...

Application of Oligonucleotide Activation to Restriction Endonuclease NarI
Restriction endonuclease NarI cleaves DNA using a two-site mechanism, placing it in the Type IIe class of restriction endonucleases. Although these enzymes have very useful recognition sequences, the two-site mechanism limits the practical application ...
