Trade-off between canonical and unusual recombination sites promotes diversity and stability of gene cassette arrays of mobile integrons [PDF]

Scientific Reports
Mobile integrons are the most efficient mechanism of Gram-negative bacteria to resist antimicrobial changing pressures in the nosocomial niche. Integron’s integrases mediate site-specific recombination of distinct DNA structures such as attI, attC and ...
