New Website Features
Two new features have been recently added to rcsb.org:
- Protein Modifications in the PDB have been mapped to the RESID database of Protein Modifications and the associated Protein Modifications Ontology (PSI-MOD). Explore these modifications with the new Protein Modification Browser, Advanced Search, and the 3D View and Sequence options on Structure Summary pages. A detailed overview is available.
- Biological assembly files for large structures are now available in PDBx/mmCIF format from Structure Summary pages. The biological assembly is the macromolecular assembly that has either been shown to be or is believed to be the functional form of the molecule. The PDBx/mmCIF format has no restrictions on the number of atoms and chains and can hold biological assemblies of any size. For more information, see PDB-101’s biological assembly tutorial. Download these data files from each Structure Summary page.
