[i] Endpoints indicate the first and last nucleotides in the genome of MG1655 that were removed in each deletion.
[ii] Descriptions of the deletions include the span of genes deleted (indicated by b-number; Blattner et al. 1997), the MG1655-specific regions (K-islands; Perna et al. 2001), and specific elements such as genes, operons, and cryptic prophages.
