23 <title>PDB Viewer</title>
27 <strong>The Jalview internal PDB Viewer</strong><br> Since
28 Jalview 2.3, the <a href="jmol.html">Jmol PDB Viewer</a> is the main
29 method for <a href="viewingpdbs.html">viewing PDB structures</a>.
30 The documentation below concerns the original Jalview PDB viewer,
31 which is only used in situations where Jmol is unavailable or cannot
35 <strong>The PDB Viewer Window</strong>
37 This interactive structure viewing window is opened by selecting
38 entries from the <strong>"Structure→"</strong>
39 submenu of the <a href="../menus/popupMenu.html">sequence id
40 pop-up menu</a>. The internal PDB viewer is not able to show
41 superpositions, so no other options are provided. Structures can
42 only be viewed for sequences which have an <a
43 href="viewingpdbs.html">associated PDB structure</a>, and the
44 PDB Viewer will only be associated with the particular alignment
45 view from which it was opened.
48 <strong>Controls</strong>
50 <p>The structure is rendered as an alpha-carbon trace. Moving the
51 mouse over the structure brings up tooltips with a residue name and
52 PDB sequence position. If a mapping exists to a residue in the
53 associated sequence, then this will be highlighted in the associated
54 view in its alignment window, and vice versa for viewing the
55 coordinates associated with a particular residue in the sequence in
56 a particular view on the alignment.</p>
57 <p>Selecting a residue highlights its associated sequence residue
58 and alpha carbon location.</p>

122 </strong><em> Colours each residue in the structure with the colour

124 rendered in the associated alignment view, including any
125 UniProt sequence features or region colourings.<br>
126 Residues which only exist in the PDB structure are coloured
127 white if they are insertions (relative to the associated
128 sequence in the alignment) and grey if they are N or C
129 terminal flanks outside the region mapped to the alignment

133 </strong><em> Assigns a random colour to each PDB chain.</em>
134 <li><strong>Charge & Cysteine<br>
135 </strong><em> Highlights cysteines in yellow, anionic (Aspartic Acid

170 <strong>Notes for PDB Viewing in the Jalview Applet</strong>
171 <p>The applet can only load PDB files by copying and pasting the
172 text into the popup window which appears when "Show PDB
173 Structure" is selected after right clicking on a sequence name.</p>
