their relationships with <a href="https://www.uniprot.org" target="_blank" rel="noopener">UniProtKB</a> entries. Protein alignments and features are loaded from RCSB PDB web services including the main data <a href="https://data.rcsb.org/" target="_blank" rel="noopener">API</a> and the <a href="https://1d-coordinates.rcsb.org/" target="_blank" rel="noopener">1D Coordinate Server</a>. These resources integrate information from multiple resources and databases. Structural features such as secondary structure, angle/distance outliers, protein-ligand binding sites or disulfide bridges, are extracted from the PDB structural data. Additionally, structural domains are annotated from <a href="https://www.cathdb.info/" target="_blank" rel="noopener">CATH</a> and <a href="https://scop.berkeley.edu" target="_blank" rel="noopener">SCOPe</a> databases. Biochemical and biomedical features are collected from the <a href="https://www.uniprot.org" target="_blank" rel="noopener">UniProtKB</a> database and mapped onto PDB sequences.</p> <a class="content-anchor" id="responsive-and-interactive-properties"></a> <h3>Responsive and Interactive Properties</h3> <ul style="list-style-type:disc;"> <li> Zoom using the mouse scroll (wheel) or the mousepad/touchpad to see more details and to show the sequence of amino acids </li> <li> To zoom using the mousepad/touchpad hover over the Sequence Annotations Viewer, and move/drag 2 fingers in an up and down motion </li> <li> Once zoomed, left click and drag to move the panel left or right (using either a mouse or touchpad) </li> <li> Left click on a feature to highlight the annotated region or right click to select and highlight a custom area </li> <li>Hovering over track features will display a legend at the top right corner of the viewer (see <a href="#feature-tooltips">Feature Tooltips</a>)</li> </ul> <div style="height: 20px;"></div><a class="content-anchor" id="conventions"></a> <h3>Conventions</h3> <ul style="list-style-type:disc;"> <li>The first track defines the sequence reference over which features are mapped </li> <li>A white circle over the start (or end) of a block indicates that the feature in its original reference does not start (or end) in that position but before (or after) </li> <li>A dashed line between blocks indicates that in the original reference the feature is connected and therefore a sequence insertion has occurred </li> <li>Color flags (blue/orange) between track titles and track features indicates feature provenance (blue for RCSB PDB and orange for third party resources) </li> </ul> <div style="height: 20px;"></div><a class="content-anchor" id="structure-summary-page--sequence-tab"></a> <h3>Structure Summary Page - Sequence Tab</h3> <p>In the Sequence Tab (e.g. <a href="/sequence/4z35" target="_blank" rel="noopener">4z35</a>) the Sequence Annotations Viewer will display the full range of available features (structural and biological annotations) and the alignments between Polymer Instances (chains) and <a href="https://www.uniprot.org" target="_blank" rel="noopener">UniProtKB</a> sequences.
