Meta-analysis of seven studies analyzing hydrogen bonds and Van der Waals interactions (VdW) in protein-RNA structures. (A) Reports across studies of the percent of hydrogen bonds in protein-RNA structures that occur with the RNA backbone (phosphate), sugar (2’-OH), or base. The percent of hydrogen bonds that occur with the protein sidechain (as opposed to the mainchain). Averages shown above each category. (B) Reports of the percent of VdWs in protein-RNA structures that occur with the RNA backbone (phosphate), sugar (2’-OH), or base. The percent of VdWs that occur with the protein sidechain (as opposed to the mainchain). Averages shown above each category. (C) Reports across studies of the average ratio of VdWs to hydrogen bonds per protein-RNA structure.
