We report here the identification and structural characterisation of post-mortem degradation and oxidation of myofibrillar proteins using high resolution mass spectrometric proteomics. Soluble muscle proteins from M. Longissimus dorsi obtained 48 h postmortem at different drip loss were separated by two-dimensional gel electrophoresis (2D-PAGE), and degradation products were identified by Fourier-transform ion cyclotron resonance mass spectrometry. Oxidation products were detected by 2D-oxyblot analysis of 2,4-dinitrophenylhydrazine (DNPH)-treated proteins using an anti-DNP antibody, and selected spots were identified by liquid chromatography-tandem mass spectrometry (LC–MS/MS). Postmortem denaturation at low drip loss was found for four contractile proteins, myosin-light chain-1; myosin regulatory light chain; α-β-tropomyosin and α-actin. The combination of 2D-PAGE and FTICR-MS was found to be a powerful approach for identification of muscle protein degradation products, providing identification of several truncation forms of creatine kinase and troponin T. The comparison of 2D-oxyblot and silver-stained 2D-gels at low and high drip loss revealed approximately 70 oxidatively modified proteins from muscle cell lysate. Oxidative modifications, representing possible biomarker candidates, were identified at Lys-170 of creatine kinase (4-hydroxynonenal), Lys-326 of actin (amino-adipic semialdehyde), and at W-169 (kynurenine) of triosephosphate isomerase.</dcterms:abstract> <dc:rights>deposit-license</dc:rights> <dc:creator>Wicke, Michael</dc:creator> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:contributor>Galetskiy, Dmitry</dc:contributor> <dcterms:title>Degradation and oxidation postmortem of myofibrillar proteins in porcine skeleton muscle revealed by high resolution mass spectrometric proteome analysis</dcterms:title> <dcterms:hasPart rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/348/2/Przybylsk.pdf"/> <dcterms:bibliographicCitation>First publ. in: International Journal of Mass Spectrometry ; 305 (2011), 2/3. - S. 217-227</dcterms:bibliographicCitation> <dc:contributor>Petre, Brindusa</dc:contributor> <dc:contributor>Wicke, Michael</dc:contributor> <dc:creator>Galetskiy, Dmitry</dc:creator> <dc:contributor>Bernevic, Bogdan</dc:contributor> <dc:contributor>Przybylski, Michael</dc:contributor> <dc:creator>Werner, Carsten</dc:creator> <dspace:hasBitstream rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/348/2/Przybylsk.pdf"/> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/348"/> <dc:creator>Schellander, Karl</dc:creator> </rdf:Description> </rdf:RDF>
