If you were born before the Dutch lost their first World Cup final, you may 
remember the days when "everybody" knew that PDB entry 1tim was the structure 
of chicken triosephosphate isomerase, 1hhb was human haemoglobin, 1lyz was hen 
egg-white lysozyme, etc. Unfortunately, life for a structural biologist is not 
that simple any longer. Nevertheless, occasionally it would be very handy to 
get at-a-glance information about some of the crucial details of a PDB entry or 
a list of entries.

When the Protein Data Bank in Europe (PDBe; pdbe.org) launched its redesigned 
website recently, we also introduced PDBlogos and PDBprints. PDBlogos are 
stylised, intuitive icons that convey important information about a PDB entry 
(e.g., the experimental technique, the source organism of the sample, or the 
presence of a ligand). PDBprints (short for "PDB fingerprints") are collections 
of PDBlogos displayed in a specific order, where each icon represents a 
well-defined category of information (and where clicking on any icon will take 
you to a webpage with more information about that aspect of the PDB entry of 

PDBprints are used in a number of places already, e.g.:

- at the top of PDBe's plain-English summary page for every PDB entry (e.g.: 

- in lists of PDBe database-search results (e.g.: 

- at the top of EDS summary pages (e.g.: 

A number of other (structural) bioinformatics resources are also considering 
incorporating PDBprints on their webpages. In fact, they are very easy to 
include in *any* webpage as evidenced by this page:

on how to include them in your own webpages) point your browser to:


We hope that you will find PDBprints useful and we value your feedback.
