Genome map of Helicobacter pylori strain B38. From outside to inside: -GC skew (window 2500, step 500) in blue. -Total CDSs (green) with pseudogenes/partial genes (purple). -CDSs coding for hypothetical restriction/modification systems (purple), phage proteins (orange), or insertion sequences (ISHp609) (green). -Total CDSs according to the matrix defined for gene identification (matrix n°1 in red, matrix N°2 in black, matrix n°3 in green). -RNA (rRNA in green, tRNA in purple and misc_RNA in red). -Rule. -GC% (window 5000, step 2000) in yellow.Red arrow indicates the position of the origin of replication.
