Cite a PDB structure entry using its PDB ID and corresponding primary reference. For example:
PDB ID: 102L
D.W. Heinz, W.A. Baase, F.W. Dahlquist, B.W. Matthews (1993) How Amino-Acid Insertions are Allowed in an Alpha-Helix of T4 Lysozyme Nature 361:561.
An entry without a published reference can be cited with the PDB ID, author names, and title:
PDB ID: 1CI0
W. Shi, D.A. Ostrov, S.E. Gerchman, V. Graziano, H. Kycia, B. Studier, S.C. Almo, S.K. Burley, New York Structural GenomiX Research Consortium (NYSGXRC). The Structure of PNP Oxidase from S. cerevisiae
An entry may also be referenced using its Digital Object Identifier (DOI). The DOIs for PDB entries all have the same format: 10.2210/pdbXXXX/pdb, where XXXX is replaced with the PDB ID (e.g., 10.2210/pdb4hhb/pdb)
The DOI can be used as part of a URL (doi.org/10.2210/pdb4hhb/pdb), or can be entered in a DOI resolver (http://www.crossref.org/) to automatically link to the entry on the PDB FTP archive (ftp://ftp.wwpdb.org).
The wwPDB should be referenced with the URL www.wwpdb.org and the following citation:
