Abstract:
MS2DB+ is an open-source platform-independent web application for determining, in polynomial time, the disulfide linkages in proteins using tandem mass spectrometry (MS/MS) data. It utilizes an efficient approximation algorithm which allows the consideration of multiple ion-types (a, a(o), a*, b, b(o), b*, c, x, y, y(o), y*, and z) in the analysis. Once putative disulfide bonds are identified, a graph optimization approach is used to obtain the most likely global disulfide connectivity pattern.

01:33Peptide Identification Using Tandem Mass Spectrometry
Tandem mass spectrometry, also known as MS/MS or MS2, is an analytical technique that employs two mass analyzers. Essentially it is a series of mass spectrometers that helps isolate a particular biomolecule and then helps study its chemical properties.
This technique helps gather information regarding the protein from which the peptide was obtained and to study the peptides’ amino acid sequence. Identifying peptides from a complex mixture is an important component of the growing field of...

01:19MALDI-TOF Mass Spectrometry
Mass spectrometry is a powerful characterization technique that can identify and separate a wide variety of compounds ranging from chemical to biological entities, based on their mass-to-charge ratio (m/z). The instruments that allow this detection, known as mass spectrometers, have three components: an ion source, a mass analyzer, and a detector. These spectrometers differ based on the nature of their ion source and analyzers.Matrix-assisted laser desorption ionization (MALDI) is a commonly...
