The SWISS-PROT database contains high-quality annotation, is non-redundant and cross-referenced to many other databases. SWISS-PROT is accompanied by TrEMBL, a computer-annotated supplement, which contains the translations of all coding sequences (CDS) present in the EMBL Nucleotide Sequence Database, which are not yet integrated into SWISS-PROT.

An experimental bioinformatics server. Classifies protein sequences as homodimers or non-homodimers. Applications: metabolic reconstruction, protein structure and function assignment, and drug-design.

In collaboration with the Munich Information Center for Protein Sequences (MIPS) and the Japanese International Protein Sequence Database (JIPID) maintains the PIR-International Protein Sequence Database --- a comprehensive, annotated, and non-redundant set of protein sequence databases in which entries are classified into family groups and alignments of each group are available.

A database built from Pfam, PRINTS and PROSITE.

Method for finding 3-D similarities in protein structures from the UCSD Supercomputer Center.

Bioinformatics research group offering organism specific information (Yeast, Cress) as well as search tools for public databases.

Online backtranslation tool for translating a protein sequence into a DNA sequence. The codon usage can be downloaded from a database and adjusted manually for each amino acid, if required. Java applet.

Provides automatic hierarchical classification of proteins sequences.

Most widely used server for analysing protein sequences, searching protein databases, and predicting protein structure - from Columbia Univ.

Includes WebOligoMelt (Annealing temperature of oligonucleotides), Virtual Ribosome (translate nucleotide sequences into peptides), and SeqScanGraph (graph melting temperature along nucleotide chain).
