A web interface that makes Circular dichroism (CD) and linear dichroism (LD) calculations available for the use of non-theoreticians, thus considerably improving the access to such calculations. Protein Data Bank (PDB) files can be processed by the hundreds and calculated spectra are sent to the user directly. The development of the interface spawned the Perl library ParsePDB.pm, which provides quick access to the parsed content of a PDB file in just one compact library.
Produces circular dichroism spectra from protein atomic coordinate file. PDB2CD utilizes a combination of structural features within the conformation of a protein; not only its percentage secondary structure content, but also the juxtaposition of these structural components relative to one another, and the overall structure similarity of the query protein to proteins in our data set.
