Rules Governing Selective Protein Carbonylation
BACKGROUND Carbonyl derivatives are mainly formed by direct metal-catalysed oxidation (MCO) attacks on the amino-acid side chains of proline, arginine, lysine and threonine residues. For reasons unknown, only some proteins are prone to carbonylation. METHODOLOGY/PRINCIPAL FINDINGS we used mass spectrometry analysis to identify carbonylated sites in: BSA that had undergone in vitro MCO, and 23...
متن کاملIdentification of aflatoxins by quadrupole mass spectrometry/mass spectrometry.
MS/MS daughter experiments were recorded for aflatoxins B1, B2, G1, G2, M1, M2, and aflatoxicol, using 3 ionization modes. Daughters were recorded from the molecular ion (M+) using electron impact ionization (EI). Daughters from the protonated molecules (MH+) were recorded in the positive ion mode and the daughters from the molecular anion (M-) were recorded in the negative ion mode using chemi...
متن کاملIdentification of protein-bound carbohydrates by mass spectrometry.
This review outlines the use of modern methods of mass spectrometry, mainly based on electrospray ionization and matrix-assisted lased desorption/ionization, for the identification of protein-bound carbohydrates. The techniques are briefly described together with methods for glycan release and purification prior to mass spectrometry. Fragmentation of glycans, produced under various conditions, ...
متن کاملTwo different Methods in Protein Identification by Mass Spectrometry
There are tow major methods that are widely used for protein identification by mass spectrometry: MALDI-TOF based protein fingerprinting and LC-MS/MS based peptide sequencing. In the MALDI-TOF based protein fingerprinting method, a sample is digested with certain proteolytic enzyme (usually trypsin) and one MS spectrum is acquired which generates the massed of all peptides (or MH+), and these m...
متن کاملData Mining in Protein Identification by Tandem Mass Spectrometry
Protein identification (sequencing) by tandem mass spectrometry is a fundamental technique for proteomics which studies structures and functions of proteins in large scale and acts as a complement to genomics. Analysis and interpretation of vast amounts of spectral data generated in proteomics experiments present unprecedented challenges and opportunities for data mining in areas such as data p...
