GC content of the CGSP14 chromosome. The GC content is calculated using the sliding-window technique (window size = 10 000 bp; shift size = 1 000 bp). Zero of the Y axis indicates the average GC content of the genome, which is 39.5%. Black arrows indicate transposons and potential genomic islands in the S. pneumoniae genome. A, lantibiotic synthesis gene cluster; B, Tn3872-like transposon; C, capsular locus; D, 19 kb inversion; E, possible phage remnant; F, putative resistance island; G, Tn2008; H, cell wall surface anchor family protein.
