Annotates eukaryotic genomes with peptide sequences obtained from mass spectrometry (MS) experiments. PeptideAtlas is a compendium of observations of peptides and associated annotations, based on a large number of contributed data sets. It also supports targeted proteomics workflows, such as selected reaction monitoring (SRM), by allowing the researcher to identify suitable proteotypic peptides to target and to estimate approximate retention time for the target peptides.
An extensively curated database of high-resolution tandem mass spectra that are arranged into spectral trees. mzCloud represents a key conceptual shift towards a modern mass spectral database. This tool is a scientifically solid and computationally robust platform for the identification of small molecules using tandem mass spectrometry. It offers a web-based interface providing a number of search, visualization and data processing tools. It also comprises curated databases of high and low resolution MSn spectra acquired under a number of experimental conditions which address the spectra reproducibility problem.
An endogenous peptide database to aid mass spectrometric identifications. In the identification process the experimental peptide masses are compared with the peptide masses stored in SwePep both with and without possible post-translational modifications. This intermediate identification step is fast and singles out peptides that are potential endogenous peptides and can later be confirmed with tandem mass spectrometry data.
Hosts a library of glycoproteins with their corresponding N-glycosites. SRMAtlas permits users to validate biomarker candidates by providing a collection of selected reaction monitoring (SRM) assays produced through three different mass spectrometric platforms. Users browse the database through five panels allowing transitions querying, transitions lists downloading, the browsing of specific builds and access to PeptideAtlas SRM Experiment Library (PASSEL) data and experiments.
Gives access to comprehensive, annotated mass spectral reference collections from various organisms and proteins. NIST Libraries of Peptide Tandem Mass Spectra are useful for the rapid matching and identification of acquired mass spectrometry (MS)/MS spectra. Peptide mass spectrum libraries can be used for direct peptide identification, validation of peptides identified by sequence search programs, organization and identification of recurring, unidentified spectra, detection of internal standards, biomarkers, and target proteins and subtraction of a component from a mixture spectrum.
