Fig. 3

Average patterns of tRNA concentration of the codons around a number of protein functional and structural features. Same representation as in Figs. 2 and 3, except that the X axis now represents codons (residues) instead of nucleotides (although the region covered is the same) and the [tRNA] scale (Y axis) is inverted to maintain the correspondence between high values and (potentially) slow translation, so as to compare with the previous figures. The red line is a smoothing of the data done with a window of 2 residues (6 nucleotides). Equivalent plots for all the protein features studied are available in the Additional file 3
