Description of Chi sites in E. coli and H. influenzae genomes.

Genome Chi sequence Nr. occurrences
E. coli 5'-GCTGGTGG-3' 761
oriC – 3,923,500 (bp)
terC – 1,588,800 (bp)
H. influenzae 5'-GGTGGTGG-3' 77
oriC – 603,000 (bp) 5'-GCTGGTGG-3' 56
terC – 1,518,000 (bp) 5'-GTTGGTGG-3' 63
5'-GNTGGTGG-3' 5'-GATGGTGG-3' 28
5'-GSTGGAGG-3' 5'-GGTGGAGG-3' 11
5'-GCTGGAGG-3' 7

The number of occurrences of Chi motifs in the genomes shows that they are overrepresented in E. coli (761 occurrences) but not in H. influenzae (maximum of 77 occurrences).
