CombSearch
Attempts to provide a unified interface to query several protein identification tools accessible on the web. Currently it includes PeptIdent, TagIdent and MultiIdent from ExPASy, MS-Fit from ProteinProspector, ProFound from PROWL and PeptideSearch from EMBL Protein and Peptide Group.

PeptideSort
Shows the peptide fragments from a digest of an amino acid sequence.

PeptideSearch
Protein identification by peptide mapping or peptide sequencing.

PROPSEARCH
Compositional search using experimental Amino Acid Analysis data.

ProteinProspector
Tools for mining sequence databases in conjunction with Mass Proteometry experiments.

PROWL
Provides an interactive environment for protein analysis that can be easily accessed with any web browser over the Internet.

ProteinInfo
A tool for retrieval and analysis of information from protein sequence databases.

ProFound
A tool for searching a protein sequence database using information from mass spectra of peptide maps.

PepFrag
A tool for searching protein or nucleotide sequences using information from fragmentation mass spectra of peptides.

ExPASy Proteomic Tools

• AACompIdent - Identify a protein by its amino acid composition
• AACompSim - Compare the amino acid composition of a SWISS-PROT entry with all other entries
• MultiIdent - Identify proteins with pI, Mw, amino acid composition, sequence tag and peptide mass fingerprinting data
• PeptIdent - Identify proteins with peptide mass fingerprinting data, pI and Mw Experimentally measured, user-specified peptide masses are compared with the theoretical peptides calculated for all proteins in SWISS-PROT, making extensive use of database annotations
• TagIdent - Identify proteins with pI, Mw and sequence tag, or generate a list of proteins close to a given pI and Mw
• FindMod - Predict potential protein post-translational modifications and potential single amino acid substitutions in peptides.
• GlycoMod - Predict possible oligosaccharide structures that occur on proteins from their experimentally determined masses
• GlycanMass - Calculate the mass of an oligosaccharide structure
• PeptideMass - Calculate masses of peptides and their post-translational modifications
• ProteinProspector - A variety of tools from UCSF (MS-Fit, MS-Tag, MS-Digest, etc.) for mining sequence databases in conjunction with mass spectrometry experiments
• PROWL - Protein chemistry and mass spectrometry resource
• PeptideSearch - Peptide mass fingerprint tool
• MOWSE - Peptide mass search tool from Daresbury Laboratory
• Mascot - Peptide mass fingerprint, sequence query and MS/MS ion search
• CombSearch - An experimental unified interface to query several protein identification tools
