Comparison of XbaI cleavage sites among six S. typhimurium strains.

Notes:a, XbaI cleavage sites numbered according to their appearance order in LT2 starting from the “beginning” of the genome, i.e., gene thrL.b, One gene ID, such as STM0557, means that the XbaI cleavage site falls in a gene; two gene IDs, such as STM1331–STM1332, mean that the XbaI cleavage site falls in an intergenic region between two genes.c and d, start and end nucleotide positions, respectively of a gene or an intergenic region between two genes.
