- Genetic map of pWR100 of Shigella flexneri

- Genetic map of the pgm locus of Yersinia pestis

- GC content of the pgm locus of Yersinia pestis
Genetic map of pWR100. The position and direction of transcription of the various genes and ORFs are indicated by arrows. ORFs for which no function could be proposed are labelled according to their coordinates (in kb) on the sequence. Pseudogenes, i. e. genes truncated or inactivated by frameshifts, are indicated in parenthesis. The colours refer to the G+C content of each ORF: red, <40%; blue, between 40 and 50%; green, >50%. The position of IS sequences is indicated by yellow bars

Map of the pgm locus and flanking regions showing the position and orientation of known genes and coding sequences (CDS). We used the following functional categories: related to virulence (red); phage related functions (light blue); transport proteins (dark blue); regulatory proteins (purple); nitrogen and carbon metabolism (brown); miscellaneous (yellow); insertion elements (black); proteins of unkonwn function (green). Thick lines below the gene map indicate: Grey, flanking regions, black, pigmentation segment and blue, HPI. Numbers at the right end of the map indicate the scale in kb.

Distribution of the base composition of the CDS within the 119 kb region sequenced. The DNA sequence was analyzed for the base composition by using GMP Tool Box (unpublished) with a window size of 1000 bases and shifted each time of 250 bp. Because of the difference in average size of the genes present on the HPI and the pigmentation segment, the G+C content was calculated only from the CDSs. Intergenic regions were not considered.The percentage of G+C is indicated. The thick line below indicates the region defined as HPI (red) and as pigmentation segment (black).
