Bacterial conjugation: a potential tool for genomic engineering.
نویسندگان
چکیده
Bacterial conjugation is a mechanism for horizontal DNA transfer with potential for universal DNA delivery. The conjugal machinery can be separated into three functional modules: the relaxosome, the coupling protein, and a type IV protein secretion system. Module interchangeability among different conjugative systems opens up the possibility of "a la carte" engineering of DNA delivery into virtually any cell type.

Site-Specific Integration of Foreign DNA into Minimal Bacterial and Human Target Sequences Mediated by a Conjugative Relaxase
BACKGROUND Bacterial conjugation is a mechanism for horizontal DNA transfer between bacteria which requires cell to cell contact, usually mediated by self-transmissible plasmids. A protein known as relaxase is responsible for the processing of DNA during bacterial conjugation. TrwC, the relaxase of conjugative plasmid R388, is also able to catalyze site-specific integration of the transferred D...

متن کاملCRISPR-Cas: From the Bacterial Adaptive Immune System to a Versatile Tool for Genome Engineering.
The field of biology has been revolutionized by the recent advancement of an adaptive bacterial immune system as a universal genome engineering tool. Bacteria and archaea use repetitive genomic elements termed clustered regularly interspaced short palindromic repeats (CRISPR) in combination with an RNA-guided nuclease (CRISPR-associated nuclease: Cas) to target and destroy invading DNA. By choo...
