Cloning and characterization of the genes of the CeqI restriction—modification system

The International Journal of Biochemistry & Cell Biology, 1997
Two genes from Corynebacterium equii, a Gram-positive bacterium producing the CeqI restriction-modification enzymes were cloned and sequenced. In vivo restriction experiments, DNA and amino acid sequence data suggest that the two genes code for the endonuclease and the methyltransferase enzymes. However, when the two genes are expressed in E.

GATC-specific restriction-modification systems in ruminal bacteria

Folia Microbiologica, 2004
The GATC-specific restriction and modification activities were analyzed in 11 major bacterial representatives of ruminal microflora. Modification phenotype was observed in 13 out of 40 ruminal strains. MboI isoschizomeric restriction endonucleases were detected in 10 bacterial strains tested; three strains lacked any detectable corresponding ...

Polymorphism of Bacterial Restriction-Modification Systems: The Advantage of Diversity

Evolution, 1994
Bacterial restriction-modification systems provide defense against foreign DNA by using a self versus nonself recognition mechanism. A great diversity of recognition motifs is maintained in natural populations. Circumstantial evidence suggests that defense against bacteriophage viruses favors this diversity.

Comparison of the Homologous SfeI and LlaBI Restriction–Modification Systems

Molecular Biology, 2002
A fragment containing the SfeI restriction-modification system (RMS) operon was cloned from a Streptococcus faecalis SE72 plasmid. Nucleotide sequence analysis revealed its high (99.2%) homology to the operon for Lactococcus lactis subsp. cremoris W56 LlaBI RMS recognizing the same site, 5'-CTRYAG-3'.

Evolution of restriction-modification systems

2018
Restriction Modification (R-M) systems prevent the invasion of foreign genetic material into bacterial cells and are therefore important in maintaining the integrity of the host genome. The spread of antibiotic resistance, which is proposed to occur via the transfer of foreign genes to the bacterial genome, makes the subject of R-M systems extremely ...
