  3. What we expect from a database..!! • Sequence, functional, structural information, related bibliography • Well Structured and Indexed • Well cross-referenced (with other databases) • Periodically updated • Tools for analysis and visualization

  4. Biological Databases • Sequence databases • Structure databases

  5. Nucleotide databases • Protein databases Sequence databases

  6. Sequence databases

  7. Nucleotide databases • International Nucleotide Sequence Database Collaboration (INSDC) • NCBI • EMBL • DDBJ

  8. Standard contents of a sequence database • Sequences • Accession number • References • Taxonomic data • Annotation/curation • Keywords • Cross-references • Documentation

  9. NCBI • Very comprehensive biological database • GENBANK: The nucleotide sequence database • Provides 42 different resource • Provides a simple and easy to use web interface

  10. Sequence submission: done using Bankit or Sequin • Search Engine for data retrieval: Entrez • Retrieves information across all the resources under NCBI Example: PubMed, taxonomy, SNP, PubChem etc.

  11. Tools for analysis • BLAST • Primer-BLAST • B-Link • ORF finder • Genome workbench

  12. Protein Sequence databases • UniProt • PFAM • Gene Index project

  13. UniProt • Universal Protein Resource • Formed through the merger of : • SIB • EBI-SwissProt • TrEMBL • PIR-PSD

  14. Entry names are often the names of the gene followed by the species. • Accession numbers are of the following format: • e.g. P26367 (PAX6_HUMAN)

  15. Uniprot features Blast Align Retrieve ID mapping

  16. Pfam • Proteins contain conserved regions • Based on the conserved regions, proteins are classified into families • Provides links to external databases like PDB, SCOP, CATH etc.

  17. Pfam: Features • Sequence search • View Pfam family • View a clan • View a sequence • View a structure • Keyword search

  18. Gene Indices • Project aimed at indexing genes and their variants in the various genome sequences. • Creating a catalogue of genes in a wide range of organisms • Reduce redundancy

  19. Gene Indices Software Tools • TGI Clustering tools • Clview • SeqClean • Cdbfasta/cdbyank

  20. Structural databases

  21. PDB – Protein Data Bank • CATH • SCOP – Structural Classification of Proteins

  22. wwPDB • Contains information about experimentally determined structures of proteins, nucleic acids, and complex assemblies • RCSB-PDB, PDBe, PDBj, BMRB – repositories of protein structure data • Files in PDB, mmCIF, PDBML/XML formats

  23. Advanced search – provides comprehensive information about a protein. • Sequence info, domain info, sequence similarity, literature, apart from the details of the structure. • Cross referenced to SCOP and CATH

  24. CATH • Classification of proteins based on domain structures • Each protein chopped into individual domains and assigned into homologous superfamilies. • Hierarchial domain classification of PDB entries.

  25. CATH hierarchy • Class –derived from secondary structure content is assigned automatically • Architecture – describes gross orientation of secondary structures, independent of connectivity • Topology – clusters structures according to their topological connections and numbers of secondary structures • Homologous superfamily – this level groups together protein domains which are thought to share a common ancestor and can therefore be described as homologous

  26. SCOP • Description of structural and evolutionary relationships between all the proteins with known structures • Uses the PDB entries • Search using keywords or PDB identifiers

  27. Hierarchy in SCOP • Class • Fold • Superfamily • Family • Species
