The PDB Viewer Window -

This interactive structure viewing window is opened by selecting -the "Sequence→View PDB entry:" entry in -the sequence id pop-up menu. This -can only be done for sequences which have an associated -PDB structure.

Controls

The structure is rendered as an alpha-carbon trace. Moving the -mouse over the structure brings up tooltips with a residue name and PDB -sequence position. If a mapping exists to a residue in the associated -sequence, then this will be highlighted in the associated view in its -alignment window, and vice versa for viewing the coordinates associated -with a particular residue in the sequence in a particular view on the -alignment.

Selecting a residue highlights its associated sequence residue -and alpha carbon location.

There are three menus: -

File

- Save As
  - Saves the current view as an EPS or PNG file.
- View Mapping
  - Opens a text window showing the alignment between the - residues corresponding to alpha-carbon atoms in the PDB structure and - the residues in the associated sequence.
-
Colours
- -
- By Sequence
  - Colours each residue in the structure with the colour of its - corresponding residue in the associated sequence as rendered in the - associated alignment view, including any Uniprot sequence features or - region colourings.
  - Residues which only exist in the PDB structure are coloured white if - they are insertions (relative to the associated sequence in the - alignment) and grey if they are N or C terminal flanks outside the - region mapped to the alignment window's sequence.
- By Chain
  - Assigns a random colour to each PDB chain. -
- Charge & Cysteine
  - Highlights cysteines in yellow, anionic (Aspartic Acid or - Glutamic Acid) residues in red, and cationic (Lysine or Arginine) - residues in blue.
- Standard and User Defined Jalview - colourschemes.
  - The remaining entries apply the colourschemes available from the - standard and user defined amino - acid colours.
-

View
- These options can be turned off to improve performance when - viewing large structures, some at the expense of visual clarity. -

Wireframe
- Draws thin lines rather than thick lines for the - alpha-carbon trace.
Depthcue
- Shades the structure so parts of the structure near the front - of the view are brighter than those further away.
Z Buffering
- Applies depth sorting to correctly render occluded regions - of the backbone trace.
Show All Chains
- When turned on, shows all chains in the PDB file, not just - the one associated with a sequence in the alignment window.

Associate View
+

+ The Jalview internal PDB Viewer
Since + Jalview 2.3, the Jmol PDB Viewer is the main + method for viewing PDB structures. + The documentation below concerns the original Jalview PDB viewer, + which is only used in situations where Jmol is unavailable or cannot + operate. +

+ The PDB Viewer Window +

+ This interactive structure viewing window is opened by selecting + entries from the "Structure→" + submenu of the sequence id + pop-up menu. The internal PDB viewer is not able to show + superpositions, so no other options are provided. Structures can + only be viewed for sequences which have an associated PDB structure, and the + PDB Viewer will only be associated with the particular alignment + view from which it was opened. +

+ Controls +

The structure is rendered as an alpha-carbon trace. Moving the + mouse over the structure brings up tooltips with a residue name and + PDB sequence position. If a mapping exists to a residue in the + associated sequence, then this will be highlighted in the associated + view in its alignment window, and vice versa for viewing the + coordinates associated with a particular residue in the sequence in + a particular view on the alignment.

Selecting a residue highlights its associated sequence residue + and alpha carbon location.

+ Notes for PDB Viewing in the Jalview Applet +

The applet can only load PDB files by copying and pasting the + text into the popup window which appears when "Show PDB + Structure" is selected after right clicking on a sequence name.
