Summary
- A typical PDB entry contains 3D coordinates of the macromolecular structures that are experimentally derived using X-ray/NMR/electron microscopy
- It also contains information about secondary structure, biological assemblies, sequence mapping information (UniProt for protein and GenBank for RNA) for the proteins and nucleic acids that are present in the entry
- The PDB entry can be further explored for binding environment of ligands and other small molecules
- Every PDB entry page comes with several tabs – displaying the contents of the entry from various structural, functional and chemical perspectives in 2D and 3D.
- The citation page not only provides information about primary and associated publications related to the entry, it also displays figures and figure legends for open access publications
- The ‘Ligands and Environments’ tab lists all the chemically distinct ligands that are present in a particular PDB entry and shows their binding sites
- There are several different download options and file formats available from a PDB entry page options and file formats present from a PDB entry page
- In addition to the PDB archive files, every entry page provides download options for biological assembly files (which can be instantly viewed using any visualisation tool like Chimera, pymol etc.), sequence files and SIFTS information
