Illustration of Binding SiteHelp

Figure showing the binding site residues. Ligands are displayed as CPK. Figures were drawn with Molscript (7) and rendered with Raster3D (8). PISA coordinates (3) are used when available (all entries except NMR). Ligands do not appear on the picture when PISA fails to apply symmetry operations to ligand coordinates.

HETgroup - Residue ContactsHelp

List of binding site residues detected in this holo-structure.

Column 1 gives the position, coloured on a yellow-to-red scale depending on the number of holo-structures where the residue is in contact with a ligand.
Column 2 gives the identifier of the chain to which the residue belongs.
Column 3 gives the 3-letter amino acid code, coloured according to physico-chemical type.

The binding residues in this holo structure are listed for each ligand independently, following the ligand's unique ID.

Note that since PISA files are used whenever available, chain identifiers may differ from those in original PDB files.

LIGPLOT (only on holo-pages) is hosted at the EBI.

The LigPlot Jmol links point directly to the Jmol visualisation interface provided on the PDBSum page.

Note that due to different software used, the atomic contacts of LigPlot and LigASite do not necessarily correspond.

Download FilesHelp

Several files are provided for download:

• The XML file defining the residue-ligand contacts; this file contains data on the apo and all holo-structures.
• The XML Schema file defining the semantics of the XML file
• 3D coordinates of the structure used in constructing LigASite (PISA structure file whenever available, PDB file otherwise.
• 3D coordinates of the combined binding residues in the apo structure
• 3D coordinates of the binding residues of the holo structure (only on the holo page)

Coordinate files are in PDB format.
