Two Two-Sample-Logos of the position-specific residue composition surrounding the ubiquitination sites and non-ubiquitination sites, which were inferred from Radivojac_dataset (A) and Cai_dataset_1 (B), respectively.

<p>These two logos were prepared using the web server <a href="http://www.twosamplelogo.org/" target="_blank">http://www.twosamplelogo.org/</a> and only residues significantly enriched and depleted surrounding ubiquitination sites (<i>t</i>-test, <i>P</i><0.05) are shown.</p>
