Every year the online journal Nucleic Acids Research devotes its January issue (http://nar.oxfordjournals.org/archive/) to databases in cheminformatics and bioinformatics. Among the more than 1000 databases listed here, this page has a classified listing of databases devoted to nucleic acid and proteins sequences, structure of small molecules, proteomics, and metabolic and signaling pathways.
Contains structures of just under 100,000 proteins and nucleic acids. A “detailed view” gives such information as the space group, the primary structure (amino acid or base sequence), the resolution of the structure, and a citation to the primary literature.
Provides a wide variety of resources mainly oriented to assist the propagation and standarization of protein annotation. PIR has many protein databases and analysis tools freely accessible to the scientific community, including the Protein Sequence Database (PSD), the first international database. It also has UniProt, a single worldwide database of protein sequence and function created by unifying the PIR-PSD, Swiss-Prot, and TrEMBL databases.
Universal Protein Resource (UniProt) provides the scientific community with a single, centralized, authoritative resource for protein sequences and functional information. It is a central repository of protein sequence and function created by joining the information contained in Swiss-Prot, TrEMBL, and PIR.
