The APECO1 and S88 pheV islands are virtually identical (99% at the nucleotide level); the transposition of a 2,581-nt insertion sequence is the only substantial difference (data not shown).
The size was calculated from the first nucleotide of pheV to the last nucleotide of the phe′V direct repeat. No repeat was identified in GI-ED1a-pheV or GI-IAI39-pheV, and the right-hand junction was taken as the breakpoint adjacent to the kpsF locus. E24377A contains a composite arrangement of two islands, similar to VR50 (data not shown).
The GenBank accession number for the complete genome sequence, where available. Accession numbers in parentheses refer to GenBank accession numbers for genomic islands, if published separately prior to the genome sequence. AF081285 covers only 13,710 bp of the CFT073 genomic island.
