PDBe PyMOL plugin

PDBe’s PyMOL plugin provides an easy way to visualise PDB data (and annotations?) in PyMOL. This plugin allows easy access to annotation of entities, domains and validation for PDB entries based on PDBe API.

Installation

The PDBe PyMOL plugin works on PyMOL 1.6 or later

PyMOL 1.6

Download the plugin from the following URL:


PyMOL 1.7 or later

Open the “plugin manager” Enter the following url in the “Install from PyMOL Wiki or URL

This will add the following items to the Plugins menu. PDBe Entity Loader PDBe Domain Loader PDBe Validation Loader Assembly Loader

Screenshot of the menu


Screenshot of the PyMOL plugin menu with the PDBe plugin installed


To use each component click the menu item in the Plugins menu and then enter and PDB ID into the dialogue box.

PDBe Loader

This displays chemically distinct molecules, domains which make up a PDB entry. It also displays the assemblies within a PDB entry.

Chemically distinct molecules which make up a PDB entry, including proteins, nucleic acids and ligands, are highlighted. Each molecule is given a unique colour and selected as a different object. Polymers (protein, DNA and RNA chains) are shown as cartoon or ribbon representation and ligands are shown as spheres. Pfam, SCOP and CATH domains within a PDB entry are highlighted. Each domain is coloured in a different colour and selected as a different object. This enables each domain to be turned on and off with PyMOL. Assemblies annotated within a PDB entry are highlighted. This requires pymol 1.76 or later.

All PDBe annotations show in PDB entry 3unb

PDBe Molecule Loader

This highlights the chemically distinct molecules which make up a PDB entry, including proteins, nucleic acids and ligands. Each molecule is given a unique colour and selected as a different object. Polymers (protein, DNA and RNA chains) are shown as cartoon or ribbon representation and ligands are shown as spheres.

In the below example the distinct molecules in PDB entry 3l2p are shown.


Distinct molecules in PDB entry 3l2p


PDB Domain Loader

This highlights the Pfam, SCOP and CATH domains within a PDB entry. Each domain is coloured in a different colour and selected as a different object. This enables each domain to be turned on and off with PyMOL.

The CATH domains in PDB entry 3b43 are highlighted in the figure below.

PDBe Validation Loader

This overlays geometric validation on a PDB entry. Geometry outliers are coloured as per the PDB validation report: Residues with no geometric outliers are shown in green Residues with one geometric outliers are shown in yellow Residues with two geometric outliers are shown in orange Residues with three or more geometric outliers are shown in red.

Geometric validation is shown on PDB entry 2gc2

Assembly Loader

This highlights the assemblies within a PDB entry. This requires pymol 1.76 or later.

Assemblies are shown within PDB entry 3unb, with each assembly as an object in pymol and coloured in a distinct colour.
