Control experiments to show the influence of overrepresented OMP classes. OMP classes OMP.8 (Figure 9A), OMP.12 (Figure 9B), OMP.16 (Figure 9C) and OMP.22 (Figure 9D) were removed and only organisms with more than 20 unique peptides were used in the clustering. Peptides belonging to OMP.nn and OMP.hypo (OMPs with unknown strand number and function) were not removed from the data set during the control experiments. Color legends are similar to the Figure 1A.
