Actinomycete integrative and conjugative pMEA-like elements of Amycolatopsis and Saccharopolyspora decoded.
Actinomycete integrative and conjugative elements (AICEs) are present in diverse genera of the actinomycetes, the most important bacterial producers of bioactive secondary metabolites. Comparison of pMEA100 of Amycolatopsis mediterranei, pMEA300 of Amycolatopsis methanolica and pSE211 of Saccharopolyspora erythraea, and other AICEs, revealed a highly conserved structural organisation, consistin...
متن کاملAssembly and transfer of tripartite integrative and conjugative genetic elements.
Integrative and conjugative elements (ICEs) are ubiquitous mobile genetic elements present as "genomic islands" within bacterial chromosomes. Symbiosis islands are ICEs that convert nonsymbiotic mesorhizobia into symbionts of legumes. Here we report the discovery of symbiosis ICEs that exist as three separate chromosomal regions when integrated in their hosts, but through recombination assemble...
متن کاملThe hidden life of integrative and conjugative elements
Integrative and conjugative elements (ICEs) are widespread mobile DNA that transmit both vertically, in a host-integrated state, and horizontally, through excision and transfer to new recipients. Different families of ICEs have been discovered with more or less restricted host ranges, which operate by similar mechanisms but differ in regulatory networks, evolutionary origin and the types of var...
متن کاملThe dualistic nature of integrative and conjugative elements
Integrative and conjugative elements (ICEs) are mobile genetic elements that play a key role in bacterial adaptation. Such elements are found in almost every bacterial genera and species, and often code for adaptive traits conferring selective advantages to their host. ICEs maintain by integrating into and replicating along with a replicon of the host genome. ICEs can propagate by conjugative t...
متن کاملThe extended regulatory networks of SXT/R391 integrative and conjugative elements and IncA/C conjugative plasmids
Nowadays, healthcare systems are challenged by a major worldwide drug resistance crisis caused by the massive and rapid dissemination of antibiotic resistance genes and associated emergence of multidrug resistant pathogenic bacteria, in both clinical and environmental settings. Conjugation is the main driving force of gene transfer among microorganisms. This mechanism of horizontal gene transfe...
