From: DNA indels in coding regions reveal selective constraints on protein evolution in the human lineage

Figure 4

Indel frequencies in different structural regions of proteins. Frequency distribution of indel events in the four secondary structure categories helix, sheet, turn and no structure. The background distribution is the relative fraction of amino acids residing in each structure among all analyzed proteins. Error bars were calculated by , where N i is the total number of indels in structure i.
