Genetic analysis of nitrate and tetrathionate reductase-less mutants of Salmonella typhimurium and the comparison of the trp region of this organism with that of Escherichia coli lead to the conclusion that the inversion involves the whole segment between ttr and chl C genes, i.e. approximately 10 percent of the genome.
