FIG. 2.

Nucleotide sequences with IS621 at 10 loci in the ECOR28 chromosome. (A) Nucleotide sequences with IS621 at three loci in the region corresponding to the 0- to 10-min region of the E. coli K-12 map. The nucleotide sequence without IS621 at each position in the E. coli K-12 (MG1655) chromosome is shown for comparison. Two types of REP sequences that have the highest homology to the sequences at the 10 loci are shown in bold. Palindromic sequences in REP are indicated by short horizontal arrows. Note that each element is flanked by 2-bp sequences (in boxes). (B) Nucleotide sequences with IS621 at seven loci located outside of the 0- to 10-min region. IS621 is inserted into the 2-bp sequences shown in boxes. The nucleotide sequence without IS621 at each position in the E. coli K-12 (MG1655) chromosome is shown for comparison. Note that REP sequences at five positions (kb 1814.3, 1952.5, 2840.5, 4372.1, and 4468.0) are in a reverse orientation.
