Gene cassette transcription in a large integron-associated array [PDF]
BMC Genetics, 2010 Background The integron/gene cassette system is a diverse and effective adaptive resource for prokaryotes. Short cassette arrays, with less than 10 cassettes adjacent to an integron, provide this resource through the expression of cassette-associated ...

Novel Gene Cassettes and Integrons [PDF]
Antimicrobial Agents and Chemotherapy, 2001 ABSTRACT An increase in multiresistant Enterobacteriaceae was observed at one of the departments of the University Medical Center Utrecht. Nine different integrons and 17 gene cassettes were found, including the new gene cassette aadA8 . This cassette was highly related to

Gene cassettes and cassette arrays in mobile resistance integrons [PDF]
FEMS Microbiology Reviews, 2009 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

Tagging genes with cassette-exchange sites [PDF]
Nucleic Acids Research, 2005 In an effort to make transgenesis more flexible and reproducible, we developed a system based on novel 5' and 3' 'gene trap' vectors containing heterospecific Flp recognition target sites and the corresponding 'exchange' vectors allowing the insertion of any DNA sequence of interest into the trapped locus. Flp-recombinase-mediated cassette exchange was

Functional characterization of Tn1331 gene cassettes [PDF]
Journal of Antimicrobial Chemotherapy, 2008 The transposon Tn1331 possesses a region including three antibiotic resistance genes with the structure aac(6')-Ib-attC-aadA1-attI1*-bla(OXA-9)-attC, which potentially includes four gene cassettes. Experimental data on the mobility of fusion cassettes as well as those on mobility of cassettes in a genetic environment such as Tn1331, which lacks an ...

Co-assortment in integron-associated gene cassette assemblages in environmental DNA samples
BMC Genetics, 2010 Background It has been shown that integron-associated gene cassettes exist largely in tandem arrays of variable size, ranging from antibiotic resistance arrays of three to five cassettes up to arrays of more than 100 cassettes associated with the vibrios.

Structural diversity of class 1 integrons and their associated gene cassettes in Klebsiella pneumoniae isolates from a hospital in China. [PDF]
PLoS ONE, 2013 BACKGROUND: Klebsiella pneumoniae strains carrying class 1 integrons are becoming more common worldwide, and their role in the dissemination of drug resistance is significant.

Functional gene cassettes in development. [PDF]
Proceedings of the National Academy of Sciences, 1993 It has been noted in recent years that groups of genes 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 ...

Microbial biofilms on macroalgae harbour diverse integron gene cassettes. [PDF]
Microbiology (Reading)Integrons are genetic platforms that capture, rearrange and express mobile modules called gene cassettes. The best characterized gene cassettes encode antibiotic resistance, but the function of most integron gene cassettes remains unknown. Functional predictions suggest that many gene cassettes could encode proteins that facilitate interactions with ...

Gene Cassettes Potentially Encoding Fosfomycin Resistance Determinants [PDF]
Antimicrobial Agents and Chemotherapy, 2005 Gene cassettes are small mobile genetic elements that are found in arrays of one or more cassettes within an integron (5, 9). In addition to a single open reading frame, or sometimes two, each cassette contains a unique recombination site that belongs to a family of sites known as 59-be (59-base elements).
