The proteome refers to the collection of proteins in a given biological organism or system
under a particular set of environmental conditions. The study of proteins, referred to as …

In mass spectrometry (MS)–based protein studies, peptide fragmentation analysis (ie,
MS/MS experiments such as matrix‐assisted laser desorption ionization [MALDI]–post …

Fragmentation at the Xxx-Pro bond was analyzed for a group of peptide mass spectra that
were acquired in a Finnigan ion trap mass spectrometer and were generated from proteins …

The influence of acid− base interactions on the gas-phase dissociation of a series of
protonated peptides was investigated. Peptides containing both acidic residues [aspartic …

Mass spectrometry combined with database searching has become the preferred method for
identifying proteins in proteomics projects. Proteins are digested by one or several enzymes …

A database of 5500 unique peptide tandem mass spectra acquired in an ion trap mass
spectrometer was assembled for peptides derived from proteins digested with trypsin …

Collision-induced dissociation (CID) is a common ion activation technique used to energize
mass-selected peptide ions during tandem mass spectrometry. Characteristic fragment ions …

The primary utility of trypsin digestion in proteomics is that it cleaves proteins at predictable
locations, but it is also notable for yielding peptides that terminate in basic arginine and …

Cyanobacteria and particularly Microcystis sp.(Chroococcales) are known to produce a
multitude of peptide metabolites. Here we report on the mass spectral analysis of …

An understanding of the process of peptide fragmentation and what parameters are best to
obtain the most useful information is important. This is especially true for large-scale …
