WebThe family of elements now known as conjugative transposons was first discovered in the late 1970s. The name “conjugative transposon” was given to these elements because they were normally integrated into a bacterial genome and excised only during the conjugal transfer process. WebMar 28, 2003 · Studied the functionality of conjugative transposons in Bacteroides. The work resulted in the understanding of how these transposons excise and integrate into host chromosomes. This is an ...
WebMar 21, 2024 · Transposons and integrons also showed higher prevalence on plasmids than on the ARG-carrying chromosome. Notably, integrative and conjugative elements (ICEs) carrying five types of ARGs were detected, and they may play an important role in facilitating the transfer of ARGs, particularly for tetracycline and macrolide-lincosamide … WebBoth plasmids are conjugative, capable of high-frequency, interspecies transfer, only isolated in the open-circular form and identical in molecular weight and pattern of restriction-endonuclease fragments. ... The resistance determinants of both plasmids behave as hitch-hiking transposons in cultural conditions that favour phage-mediated or ...
WebDec 1, 2002 · The term Integrative Conjugative Elements (ICE) was first proposed by Burrus et al. to describe bacterial mobile genetic elements (MGEs) that are self-transmissible, integrate into and excise... Although ICEs exhibit various mechanisms promoting their integration, transfer and regulation, they share many common characteristics. ICEs comprise all mobile genetic elements with self-replication, integration, and conjugation abilities, including conjugative transposons, regardless of the particular conjugation and integration mechanism by which they act. Some immobile genomic pathogenicity islands are also believed to be defective ICEs that have lost their ability to conjugate.

WebFeb 1, 2024 · Two ISs can flank an accessory gene, such as an ARG, to form a composite transposon. More complex transposons, such as those of the Tn3 family, transpose via the formation of a cointegrate. These still usually produce target site duplications. The most complex of transposons are the conjugative transposons, the ICEs [16]. These … grip hair waxWebNov 18, 2016 · We found that Tn916, the first conjugative transposon identified, replicates autonomously via a rolling-circle mechanism.
