Open source Java implementation of the dynamic programming algorithm Smith-Waterman for biological local pairwise sequence alignment.

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.

PIR is a non-redundant annotated protein sequence database, and analytical tools, maintained by collaboration of MIPS, in Munich and the Japanese International Protein Sequence Database (JIPID).

A database built from Pfam, PRINTS and PROSITE.

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

Provides automatic hierarchical classification of proteins sequences.

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

Ab initio predictions of protein function from protein sequence. The method works by integrating various predicted post-translational and localizational aspects of the proteins submitted.

Combines sequence and structural information for predicting the structure and/or function of your protein sequence, and can detect remote homologies beyond PSI-Blast.

3D protein structure prediction from amino acid sequence. Includes MEMSAT for transmembrane topology prediction, GenTHREADER and mGenTHREADER for fold recognition.

Secondary protein structure prediction from amino acid sequence; based on a consensus from several methods including DSC, PHD, NNSSP, PREDATOR, ZPRED, and MULPRED.

Online software for protein analysis from the Swiss Institute of Bioinformatics (SIB).

Powerful, state-of-the-art, 2-D analysis software package with user-friendly interface from the Swiss Institute of Bioinformatics.

UniProt (Universal Protein Resource) is a catalog of information on proteins. It is a central repository of protein sequence and function created by joining the information contained in Swiss-Prot, TrEMBL, and PIR.

Identifies functionally important regions on the surface of a protein or domain, of known three-dimensional (3D) structure using the phylogenetic relations between close sequence homologues.

Service for detecting the multiple structural alignments of proteins. Uses the common geometrical cores between the input molecules. Does not require that all the input molecules participate in the alignment.

ESyPred3D is an automated homology modeling program getting benefit of the increased alignment performances of a new alignment strategy using neural networks. The final three dimensional structure is built using the modeling package MODELLER.

Accepts a single query protein sequence and returns the most probable Gene Ontology functional annotations in each of the three ontologies.

Predicts functional sites (linear motifs) in proteins, such as post-translational modification sites, ligand motifs, and targeting signals. Context-based rules and logical filters are applied to improve predictions.

Phyre is a free for academics service for predicting the 3-dimensional structure of a protein amino acid sequence.

Provides interactive service for matching protein structures in 3D and looking for structural homologues in PDB and SCOP databases, as well as in user-uploaded sets of structures.

A compilation of transcriptional regulatory protein factors and their cognate gene promoter elements along with DNA sequence search and analysis programs - from GBF, Braunschweig, Germany.

A database of annotated comparative protein structure models. The database includes fold assignments and alignments as well as information about putative ligand binding sites, SNP annotation, and protein-protein interactions.

Computational tool for sequence based prediction of intrinsic protein disorder and unstructured regions within a protein.

Public web service for the alignment and superposition of protein structures and the instant visualization of structural similarities.

A decision support system for protein structure comparison. It provides tools for visualising, analysing, clustering and comparing results.

Calculator with graphical user interface written in Qt library.

Integrated resource, which provides information about ligands, sequence and structure motifs, their relative position and the neighbour environment.

Resource for the prediction of antigenicity combined with functional analysis of the target protein.

An online service for predicting MHC binding regions in antigens. It also offers the proteasomal and immunoproteasomal filters to improve the applicability of results.

Scansite searches for motifs within proteins that are likely to be phosphorylated by specific protein kinases or bind to domains such as SH2 domains, 14-3-3 domains or PDZ domains.
