The information sources used by bioinformatics can be divided into i) raw DNA sequences, ii) protein sequences, iii) macromolecular structures, iv) genome sequencing, among others. A set of databases collects together patterns found in protein sequences rather than the complete sequences. Structure Database (MMDB). PROTEIN DATABASES Protein databases are more specialized than primary sequence databases. They contain information derived from the primary sequence databases. Some contain protein translations of the nucleic acid sequences. Some contain sets of patterns and motifs derived from sequence homologs. • A collection of – structured – searchable (index)-> table of contents – updated periodically (release)-> new edition – cross-referenced (hyperlinks) -> … The protein motif and pattern are encoded as “regular expressions”. Users can perform simple and advanced searches based on annotations relating to sequence, structure and function. Pfam is based on the sequence alignment. It is located at the National Biomedical Research Foundation (NBRF). Since 1988 it has … It contains hundreds of thousands of protein descriptions, including function, domain structure, subcellular location, post-translational modifications and functionally characterized variants. b. In designing the individual projects (summarized in Table 2), each protein of focus had a single amino acid substitution that had been linked to a human disease, documented in the OMIM database, and had a published crystal structure available of either the exact protein or a close homolog.Ten projects were developed that met these criteria, and we plan to add more in the future. The chief objective of the development of a database is to organize data in a set of structured records to enable easy retrieval of information. A few popular databases are GenBank from NCBI (National Center for Biotechnology Information), SwissProt from the Swiss Institute of Bioinformatics and PIR from the Protein Information Resource. 6.2.2 Protein Databases (Amino Acid Sequence) PIR - International Protein Sequence Database) PIR - The Protein Sequence Database [20] was developed in the early 1960’s. They are capable of merging information from different sources and making it available in a new and more convenient form, or with an emphasis on a particular disease or organism.
