Circular representations of C. difficile chromosomes. From the outside (scale in bp): circles 1 and 2 show the position of R20291 CDS transcribed in a clockwise and anti-clockwise direction colored according to predicted function; circle 3 shows CDS unique to R20291; circle 4 shows CDS unique to both R20291 and CD196; circle 5 shows GC content; circle 6 shows GC deviation (> 0%, olive; < 0%, purple). Color coding for CDS functions: dark blue, pathogenicity/adaptation; black, energy metabolism; red, information transfer; dark green, surface-associated; cyan, degradation of large molecules; magenta, degradation of small molecules; yellow, central/intermediary metabolism; pale green, unknown; pale blue, regulators; orange, conserved hypothetical; brown, pseudogenes; pink, phage and IS (Insertion Sequence) elements; grey, miscellaneous.
