Site-specific recombination (SSR) at tRNA-Pro in B. mallei causes a 3' end repeat 26 bp downstream of the recombination site. This site contains insertion element IS407A, which is common in B. mallei genomes. This suggested that IS407A was present in other mobile genetic elements when they were originally introduced to B. mallei genomes and the recombination event was associated with tRNA-Pro.
