Integrons are natural tools for bacterial evolution and innovation. Their involvement in the capture and dissemination of antibiotic-resistance genes among Gram-negative bacteria is well documented. Recently, massive ancestral versions, the superintegrons (SIs), were discovered in the genomes of diverse proteobacterial species. SI gene cassettes with an… (More)
Superintegrons (SIs) and multiresistant integrons (MRIs) have two main structural differences: (i) the SI platform is sedentary, while the MRI platform is commonly associated with mobile DNA elements and (ii) the recombination sites (attC) of SI gene cassette clusters are highly homogeneous, while those of MRI cassette arrays are highly variable in length… (More)
The gene ere(A) of the plasmid pIP1100 is larger than originally reported and is organized as an integron gene cassette. The ere(A) gene cassette carries its own promoter and is propagated by a class 2 integron with an insertion sequence element, IS1, inserted upstream of the intI2 gene. The mobility of the ere(A) cassette has been demonstrated.
