Dear pdb-l, PDBe has created a new process to aggregate and name assemblies in the PDB based on unique assembly composition. This process allows assemblies with the same composition to be aggregated together. The assemblies can be aggregated into over 90,000 distinct compositions by mapping each component in an assembly to external databases. Over 90% of the assemblies have been named using external resources such as Complex Portal, Gene Ontology, UniProt and manual curation by PDBe annotators. This new process will allow researchers to find all assemblies that have a certain UniProt/Rfam accession or combination of accessions. Users can also find super-assemblies of an assembly which can help understand how different protein complexes interact with each other. Finally, users can find assemblies based on specific names helping to identify and study specific protein complexes that are relevant to their research.
