Histogram of GC content in proteobacterias genomes that present or lack genes tsaB and gluQ involved in t6A and GluQ modifications. The 1484 proteobacterial genomes were separated in groups depending on the presence or absence of tsaB and gluQ (indicated as GluQRS to avoid confusions with the modification) and the GC content of genome sequences was analyzed. Data is represented in histograms superposed to the histogram of the complete database of proteobacterial genomes. A) Gray: all genomes. Blue: genomes that present tsaB, but lack gluQ. B) Gray: all genomes. Orange: genomes that lack tsaB and present gluQ. C) Gray: all genomes. Purple: genomes that present tsaB and gluQ. D) Gray: all genomes. Pink: genomes that lack tsaB and gluQ.
