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).
