Physical mapping of repetitive extragenic palindromic sequences in Escherichia coli and phylogenetic distribution among Escherichia coli strains and other enteric bacteria.

Abstract excerpt

Repetitive extragenic palindromic (REP) sequences are highly conserved inverted repeat sequences originally discovered in Escherichia coli and Salmonella typhimurium. We have physically mapped these sequences in the E. coli genome by using Southern hybridization of an ordered phage bank of E. coli (Y. Kohara, K. Akiyama, and K. Isono, Cell 50:495-508, 1987) with generic REP probes derived from the REP consensus...
