WitrynaThe F factor is often associated with Escherichia coli and appears to have been adapted by the bacterial host to act as an agent of genetic exchange and evolution. F encodes a type IV secretion system (T4SS) that enables bacterial conjugation, the transfer of DNA from a donor F + to a recipient F − cell. The delivery of DNA containing either host or … Witrynaon the mini-F plasmid (Eichenlaub et eL, 1977) and when all three origins are present on the na- tive F plasmid.

Witryna8 paź 2014 · The origins of replication ( ori) are plasmid-borne DNA sequences that direct the host cell to initiate plasmid replication and are thus essential for plasmid propagation. This is accomplished by various proteins (initiators and repressors) binding to the sequence that make up the ori. WitrynaAn oriS construct created with pUC18 could transform the polA (-) strain when RepA was supplied in trans. When the oriS region (between nucleotides 290 and 832) was ligated to an antibiotic resistance Omega fragment, the construct could be recovered as a plasmid from polA (+) strain if functional RepA was provided in trans.
