Browsing through molecular functions.
RCSB PDB's Browse Database feature explores the PDB archive using different hierarchical trees. Browsers are available to search for related terms and structures based upon the following classifications:
- Trees for Biological Process, Cellular Component, and Molecular Function are organized using the Gene Ontology (GO) Consortium's descriptions for gene products. PDB IDs and corresponding chain IDs have been mapped to GO terms by the SIFTS initiative.
- Enzyme Commission numbers. Search for enzymes by name, or by partial or full EC number.
- Membrane Transport proteins organized using Transporter Classification (TC) Database system.
- Source Organism, using organisms found in the NCBI Taxonomy database. These organisms are the source of the individual naturally-occuring polypeptides. Source organism assignment in the PDB is based on author/UniProtKB-specified polypeptide mapping.
- Genome Location of various organisms. The genomes represented are a subset of those in NCBI's genome database with curated sequences for genetic loci archived at Entrez Gene. The top level in the hierarchy is the organism's genome. Each genome expands into chromosomes, which in turn expand into a list of loci on the chromosomes. Each locus is a link to retrieve associated structures.
- MeSH (Medical Subject Headings) that appear in the entry's related PubMed abstract.
- SCOP description of evolutionary and functional relationships from SCOP: Structural Classification of Proteins.
- CATH clustering of proteins at four major levels from CATH: Protein Structure Classification.
