ASC (Active Sequences Collection) is a set of seven databases of short amino acid sequences with known biological activity. ASC contains more than 2,349 different short amino acid sequences with record-links to external genomics/literature databanks: PubMed, SwissProt, PDB, PDBSum, PDF-FINDER, CATH, MMDB, IMB, PQS, and ENZYME. The seven database subfiles are:
AIRS : Auto Immune Related Sequences (60);
BAC : Bio ACtive peptides (745);
CHAMSE : CHAMeleon SEquences (39) which have been observed to assume both assume both alpha helix and beta strand structure in 3D models of proteins.
DORRS : Database of RGD Related Sequences (129);
DVP : Delivery Vector Peptides (33);
SSP : Structure-Solved Peptides (310) -- includes PDB link;
TRANSIT : TRANsglutamination SITes (103) -- includes the
transglutaminase-type acting on the protein.
