Molecular biology: Singled out for integration

Michael Chandler1

Bacteria regularly swap genes among themselves. The structure of an enzyme that mediates the spread of certain DNA elements reveals the unusual way in which they take up residence in new genomes.

The transfer of genes among bacteria is crucial in generating diversity, allowing bacteria to adapt quickly to changing environments. Mobile DNA elements called integron cassettes are major vehicles in such gene exchange.
