Contacting ResiduesHelp

List of binding site residues detected in this protein.

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

Chain ID's of residues are not mentioned in this page because all chains in the apo-structure refer to the same protein.

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.

holo-structuresHelp

Table describing the holo-structures and ligands used to define the binding sites.

Column 1 gives the PDB ID of the holo-structure.
Column 2 gives the unique ID of the ligand; a space-separated list of HET-groups that constitute the ligand (see Methods). Each HET-group in the ligand is uniquely identified by a string in which the first four characters are the three-letter HET ID from the PDB file followed by the chain ID from the PISA file, and the last four characters are the residue sequence number from the PDB file.
Column 3 gives the number of atoms in each ligand.
Column 4 gives the number of protein-ligand inter-atomic contacts.
