Integrons and the Origin of Antibiotic Resistance Gene Cassettes
I ntegrons, which are natural genetic engineering platforms, can incorporate open reading frames and convert them to functional genes by ensuring correct expression. Although such integrons play a major role in multidrug resistance phenomena among gram-negative species, similar platforms occur in numerous bacterial species, where they can play other roles. Meanwhile, we have evidence suggesting...
متن کاملGene cassettes and cassette arrays in mobile resistance integrons.
Gene cassettes are small mobile elements, consisting of little more than a single gene and recombination site, which are captured by larger elements called integrons. Several cassettes may be inserted into the same integron forming a tandem array. The discovery of integrons in the chromosome of many species has led to the identification of thousands of gene cassettes, mostly of unknown function...
متن کاملFunctional gene cassettes in development.
It has been noted in recent years that groups ofgenes are often used at multiple stages and multiple places of development. Comparison of the functions of each group of genes in different developmental context gave rise to the notion of "functional gene cassettes." These groups of genes can often be viewed as sets of tools; each group is suited to carry out a certain operation and may serve sim...
متن کاملRAC: Repository of Antibiotic resistance Cassettes
Antibiotic resistance in bacteria is often due to acquisition of resistance genes associated with different mobile genetic elements. In Gram-negative bacteria, many resistance genes are found as part of small mobile genetic elements called gene cassettes, generally found integrated into larger elements called integrons. Integrons carrying antibiotic resistance gene cassettes are often associate...
متن کاملCassettes for PCR-mediated gene tagging in Candida albicans utilizing nourseothricin resistance.
In recent years a number of molecular tools have been reported for use in the human fungal pathogen Candida albicans, including PCR-mediated approaches for gene disruption, conditional expression and epitope tagging. Traditionally these methods have utilized auxotrophic markers; however, the availability of auxotrophic markers can be limiting and in some instances their use may also impact on t...
