Only the first macromolecule from PQS is used
for related PDB entry
For PDB entries of virus samples *.unique
PQS files are used (that contains just those symmetry generated repeats
that together describe all possible inter-chain contacts)
(1015) PQS entries having no aminoacids in them are
not annotated
Availability of annotations for PQS entries (abundant is for ProSite patterns with a high probability of occurrence and "ProSite non-abundant feature" is for structures having no SwissProt annotations, but having at least one ProSite non-abundant feature) :
