Structure and role of coupling proteins in conjugal DNA transfer.
Type IV secretory systems are transmembrane bacterial multiprotein complexes. They are pivotal for conjugation, bacterial-induced plant tumour formation, toxin secretion and mammalian pathogen intracellular activity. These systems are involved in the spread of antibiotic resistance genes among bacteria by enabling conjugative DNA transfer. When such translocons transport DNA, they require the a...
متن کاملInterdomain conjugal transfer of DNA from bacteria to archaea.
Escherichia coli transforms the methanogenic archaeon Methanococcus maripaludis at frequencies ranging from 0.2 x 10(-6) to 2 x 10(-6) per recipient cell. Transformation requires cell-to-cell contact, oriT, and tra functions, is insensitive to DNase I, and otherwise displays hallmarks of conjugation.
متن کاملThe infidelity of conjugal DNA transfer in Escherichia coli.
The accuracy of replication and transfer of a lacI gene on an F' plasmid was measured. Following conjugal transfer of the F', a small but reproducible increase (1.8-fold) in the frequency of lacI- mutations was detected. Among these, however, the frequency of nonsense mutations was 15-fold higher than in the absence of transfer. This corresponds to a 300-fold increase in the rate of base substi...
متن کاملGenomic Signatures of Distributive Conjugal Transfer among Mycobacteria
Distributive conjugal transfer (DCT) is a newly described mechanism of lateral gene transfer (LGT) that results in a mosaic transconjugant structure, similar to the products of meiosis. We have tested popular LGT detection methods on whole-genome sequence data from experimental DCT transconjugants and used the best performing methods to compare genomic signatures of DCT with those of LGT throug...
