The PDB Browser allows the user to rapidly search through the contents of the PDB Archive for entries obeying certain constraints. Many of these constraints are regular expressions while others are numerical limits . Once the constraints are set, the user can choose to view the results of the search in a number of different ways. Finally, once the search has been concluded, one can choose to display the display any entry in the archive - either as a hypertext document or as a manipulatable image using the remarkable public domain program called RasMol . Regular Expression Search You can search on a number of fields in a PDB entry.
Regular Expressions can be a very powerful tool for searching throught the archive.
This is the PDB ID Code, a 4 character code which is rarely of significance except for an easily remembered index. Compound This is a description of the molecule that was studied. Author This is a list of the Author who submitted the entry. This describes the reference to the paper written to describe th enntry. If there are any non-standard residues, they are names here.
