Distributions are compared for sites that are phosphorylated in the PDB (phos) and those that are not phosphorylated (non-phos) in the same coordinate files

In these, and succeeding phos/non-phos plots, probability (p) values of the phos and non-phos distributions arising from the same underlying population were estimated with the Mann-Whitney U test. (a) 100%, no removal of sequences. (b) Sequences culled at 25% sequence identity.<p><b>Copyright information:</b></p><p>Taken from "Charge environments around phosphorylation sites in proteins"</p><p>http://www.biomedcentral.com/1472-6807/8/19</p><p>BMC Structural Biology 2008;8():19-19.</p><p>Published online 25 Mar 2008</p><p>PMCID:PMC2291461.</p><p>
