Figure 4.

Comparison of functional category average protein size between different taxa (dataset 2). The average size of proteins of KEGG ontology (KO) categories were calculated for each taxonomic group and then plotted to each other. Each red point represents a KO category. The blue rectangle indicates the average size of all proteins of those taxa. The diagonal black line indicates identical size in given number of amino acids. Dots above the diagonal indicate proteins that are larger in y-axis species as compared to the x-axis species.
