Selfish DNA: Homing Endonucleases Find a Home
نویسنده
چکیده
Self-splicing group I introns come in two flavours - those with a homing endonuclease to promote mobility of the intron, and those without an endonuclease. How homing endonucleases and self-splicing introns associate to form a composite selfish genetic element is a question of long-standing interest. Recent work has revealed that a shared characteristic of both introns and endonucleases, the targeting of conserved sequences, may provide the impetus for the evolution of composite mobile genetic elements.

Selfish DNA: New Abode for Homing Endonucleases
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 endonucleases.
متن کاملSegH and Hef: two novel homing endonucleases whose genes replace the mobC and mobE genes in several T4-related phages
T4 contains two groups of genes with similarity to homing endonucleases, the seg-genes (similarity to endonucleases encoded by group I introns) containing GIY-YIG motifs and the mob-genes (similarity to mobile endonucleases) containing H-N-H motifs. The four seg-genes characterized to date encode homing endonucleases with cleavage sites close to their respective gene loci while none of the mob-...
متن کاملComprehensive homing endonuclease target site specificity profiling reveals evolutionary constraints and enables genome engineering applications
Homing endonucleases (HEs) promote the evolutionary persistence of selfish DNA elements by catalyzing element lateral transfer into new host organisms. The high site specificity of this lateral transfer reaction, termed homing, reflects both the length (14-40 bp) and the limited tolerance of target or homing sites for base pair changes. In order to better understand molecular determinants of ho...
متن کاملA two-plasmid bacterial selection system for characterization and engineering of homing endonucleases.
Homing endonucleases recognize long DNA sequences and generate site-specific DNA double-stranded breaks. They can serve as a powerful genomic modification tool in various industrial and biomedical applications. Here, we describe a two-plasmid bacterial selection system for characterization and engineering of homing endonucleases. This selection system couples the DNA cleavage activity of a homi...
متن کاملHoming endonucleases: DNA scissors on a mission.
Buried within the genomes of many microorganisms are genetic elements that encode rare-cutting homing endonucleases that assist in the mobility of the elements that encode them, such as the self-splicing group I and II introns and in some cases inteins. There are several different families of homing endonucleases and their ability to initiate and target specific sequences for lateral transfers ...
