MASH Suite

Link

MASH Suite is a versatile software interface for processing high-resolution mass spectrometry data. MASH Suite contains a wide range of features that allow users to easily navigate through data analysis, visualize complex high-resolution mass spectrometry data and manually validate automatically processed results.

MS-Align+

Link

MS-Align+ is a software tool for top-down protein identification based on spectral alignment that enables searches for unexpected post-translational modifications. MS-Align+ is fast in identifying unexpected post-translational modifications. In addition, MS-Align+ reports statistical significance of top-down protein identifications.

MS-DECONV

Link

MS-Deconv is a software tool for top down spectral deconvolution. MS-Deconv uses a combinatorial algorithm. The algorithm first generates a large set of candidate isotopomer envelopes for a spectrum, then represents the spectrum as a graph, and finally selects its highest scoring subset of envelopes as a heaviest path in the graph. In contrast with other approaches, the algorithm scores sets of envelopes rather than individual envelopes.

MSPathFinder

Link

Similar to database search engines for bottom-up, it takes a fasta file, a spectrum file, and a list of modifications as an input and reports proteoform spectrum matches (PrSMs) and their scores.

ProSight Lite

Link

ProSight Lite is a free Windows application for matching a single candidate protein sequence and its modifications against a set of mass spectrometric observations.

ProSight PTM

Link

ProSight PTM 2.0 allows identification and characterization of both intact proteins and peptides. ProSight Warehouses are annotated with all known post-translational modifications (PTMs), alternative splicing events and single nucleotide polymorphisms (SNPs) using Shotgun Annotation. ProSightPTM allows the user to search their tandem MS data against proteome warehouses containing the known biological complexity present in UniProt.

ProteinGoggle

Link

ProteinGoggle is an intact protein database search engine for identification of proteoforms.  It uses novel search algorithm, isotopic mass-to-charge ratio & envelope fingerprinting (iMEF).  iMEF intrinsically interpret tandem mass spectral data in situ (without deconvolution or deisotoping) with two unique strength. One is to accurately and efficiently resolve overlapping isotopic envelopes; and the other is to unambiguously separate matching product ions with ideal isotopic envelopes from non-matching product ions with non-ideal isotopic envelopes.

Proteoform Characterization Tool

Link

This tool (beta) was developed for scoring proteoforms of multiply-modified proteins. The input is: (i) an intact mass, (ii) a fragment ion dataset, (iii) a protein sequence, and (iv) the specific kinds of PTMs to be considered. The output is given as a [Phrap] score, where the higher scores are better.

Protter

Link

The ability to integrate and visualize experimental proteomic evidence in the context of rich protein feature annotations represents an unmet need of the proteomics community. Protter is a web-based tool that supports interactive protein data analysis and hypothesis generation by visualizing both annotated sequence features and experimental proteomic data in the context of protein topology. Protter supports numerous proteomic file formats and automatically integrates a variety of reference protein annotation sources, which can be readily extended via modular plug-ins.

pTop

Link

pTop is a software dedicated for the analysis of intact protein using mass spectrometry. It can support the complex data sets with ultra-modifications.

Search Engine for Multi-Proteoform Complexes

Link

Here we combine the CORUM and UniProt databases to create candidates for an error-tolerant search engine designed for hierarchical top-down analyses, identification, and scoring of multi-proteoform complexes by native mass spectrometry.

SpectroGene

Link

SpectroGene is a tool for top-down protein identification using unannotated bacterial genome. SpectroGene could be used for disocvery of previously unannotated genes as well as correction of known genes coordinates (especially, Start codons). Almost all PrSMs which are found with a standard search with a known proteome could be also identified with SpectroGene without proteome reference.

TopFIND

Link

TopFIND is the Termini oriented protein Function Inferred Database (TopFIND), an integrated knowledge-base focused on protein termini, their formation by proteases and functional implications. It contains information about the processing and the processing state of proteins and functional implications thereof derived from research literature, contributions by the scientific community and biological databases.s.

TopPIC

Link

TopPIC (TOP-Down Mass Spectrometry Based Proteoform Identification and Characterization) is a software tool for identification and characterization of proteoforms at the whole proteome level by top-down tandem mass spectra using database search. It efficiently identifies proteoforms with unexpected mutations and post-translational modifications and accurately estimates statistical significance of identifications. It uses several techniques, such indexes, spectral alignment, and a generation function method, to increase its speed, sensitivity, and accuracy.s.

YADA

Link

YADA can deisotope and decharge high-resolution mass spectra from large peptide molecules, link the precursor monoisotopic peak information to the corresponding tandem mass spectrum, and account for different co-fragmenting ion species (multiplexed spectra). YADA also enables a pipeline consisting of ProLuCID and DTASelect for analyzing large-scale middle-down proteomics data.
