  2. Mascot (software) - Wikipedia

    en.wikipedia.org/wiki/Mascot_(software)

    Mascot identifies proteins by interpreting mass spectrometry data. The prevailing experimental method for protein identification is a bottom-up approach, where a protein sample is typically digested with trypsin to form smaller peptides. While most proteins are too large, peptides usually fall within the limited mass range that a typical mass ...

  3. MOWSE - Wikipedia

    en.wikipedia.org/wiki/MOWSE

    The MOWSE algorithm was developed by Darryl Pappin at the Imperial Cancer Research Fund and Alan Bleasby at the SERC Daresbury Laboratory. [2] The probability-based MOWSE score formed the basis of development of Mascot, a proprietary software for protein identification from mass spectrometry data.

  4. Peptide mass fingerprinting - Wikipedia

    en.wikipedia.org/wiki/Peptide_mass_fingerprinting

    A typical workflow of a peptide mass fingerprinting experiment. Peptide mass fingerprinting (PMF), also known as protein fingerprinting, is an analytical technique for protein identification in which the unknown protein of interest is first cleaved into smaller peptides, whose absolute masses can be accurately measured with a mass spectrometer such as MALDI-TOF or ESI-TOF. [1]

  5. Genome-based peptide fingerprint scanning - Wikipedia

    en.wikipedia.org/wiki/Genome-Based_Peptide...

    Genome-based peptide fingerprint scanning (GFS) is a system in bioinformatics analysis that attempts to identify the genomic origin (that is, what species they come from) of sample proteins by scanning their peptide-mass fingerprint against the theoretical translation and proteolytic digest of an entire genome. [1]

  6. Protein mass spectrometry - Wikipedia

    en.wikipedia.org/wiki/Protein_mass_spectrometry

    A mass spectrometer used for high throughput protein analysis. Protein mass spectrometry refers to the application of mass spectrometry to the study of proteins.Mass spectrometry is an important method for the accurate mass determination and characterization of proteins, and a variety of methods and instrumentations have been developed for its many uses.

  7. Sequest - Wikipedia

    en.wikipedia.org/wiki/SEQUEST

    The software evaluates protein sequences from a database to compute the list of peptides that could result from each. The peptide's intact mass is known from the mass spectrum, and Sequest uses this information to determine the set of candidate peptides sequences that could meaningfully be compared to the spectrum by including only those near ...

  8. Proteomics - Wikipedia

    en.wikipedia.org/wiki/Proteomics

    Robotic preparation of MALDI mass spectrometry samples on a sample carrier. Proteomics is the large-scale study of proteins. [1] [2] Proteins are vital macromolecules of all living organisms, with many functions such as the formation of structural fibers of muscle tissue, enzymatic digestion of food, or synthesis and replication of DNA.

  9. Ribbon diagram - Wikipedia

    en.wikipedia.org/wiki/Ribbon_diagram

    Ribbon diagrams, also known as Richardson diagrams, are 3D schematic representations of protein structure and are one of the most common methods of protein depiction used today. The ribbon depicts the general course and organization of the protein backbone in 3D and serves as a visual framework for hanging details of the entire atomic structure ...
