Schematic representation of the
cag region as deduced from analysis of strain CCUG
17874. The cag integration site within the glutamate
racemase gene (glr) is shaded (a).
cag structure: the putative ORFs are represented by
arrows (b). Flanking the intervening sequence (dots),
the IS605 have a left and right end indicated with large
solid and open arrowheads. ORFs with strong similarity are indicated.
The cagII region is drawn interrupted but ordered clones
and long distance PCR give an approximate indication of the total
length, which is indicated by a continuous line. The results of amino
acid database searches are included. The name of the genes are in
boldface type. LLS, low level of similarity
(e−2 > e >
e−10); HLS, high level of similarity
(>e−50). GenBank, EBI, Swiss-Prot, and
Protein Identification Resource releases for December 31, 1995 were
used. cagT (LLS), Shigella flexnerii
