Figure 2From: Comparison of codon usage measures and their applicability in prediction of microbial gene expressivityPlots of the E. coli genome made using different measures of codon usage. The four plots were made by using measures that allow an expected codon distribution to be specified: B, MCB, ENC' or MILC. The distance of codon usage of a gene from E. coli ribosomal genes was plotted on the x axis, and the distance of codon usage of a gene from the average codon usage of E. coli was plotted on the y axis. A characteristic 'crescent moon' shape is seen on all four plots. White square represent ribosomal protein genes, while all other genes are represented by grey squares.Back to article page
