Fig 6From: Distribution and diversity of ribosome binding sites in prokaryotic genomesDistribution of Genes with Seven Most Abundant SD Motifs over COG Minor Groups. The COG subgroup classifications are identical to those in Fig. 5. The relative frequency of genes with the seven most abundant motifs within each of the COG minor categories is plotted to see if genes in a COG functional category use a specific SD motifBack to article page
