The (PCDDB) was first proposed in 2006, with the aim of providing CD and SRCD information for both the biological and
bioinformatics research communities and funding bodies.
All entries submitted undergo strict validation and curation procedures to ensure completeness, consistency and quality of the data. A web-based interface enables users to browse and query sample types, sample conditions, experimental parameters and provides spectra in both graphical display format and as downloadable text files. The entries are linked, when appropriate, to primary sequence (UniProt) and structural (PDB) databases, as well as to secondary databases such as the Enzyme Commission functional classification database and the CATH fold classification database, as well as to literature citations.
The PCDDB is available at: http://pcddb.cryst.bbk.ac.uk.
