Gel-free proteomic methodologies to study reversible cysteine oxidation and irreversible protein carbonyl formation

Boronat i Llop, Susanna, 1965-; García Santamarina, Sarela, 1978-; Hidalgo Hernando, Elena (Taylor & Francis (Routledge), 2015)

Oxidative modifications in proteins have been traditionally considered as hallmarks of damage by oxidative stress and aging. However, oxidants can generate a huge variety of reversible and irreversible modifications in ...
Is oxidized thioredoxin a major trigger for cysteine oxidation? Clues from a redox proteomics approach

García Santamarina, Sarela, 1978-; Boronat i Llop, Susanna, 1965-; Calvo, Isabel A.; Rodríguez Gabriel, Miguel; Ayté del Olmo, José; Molina, Henrik; Hidalgo Hernando, Elena (Mary Ann Liebert, Inc, 2013)

Cysteine oxidation mediates oxidative stress toxicity and signaling. It has been long proposed that the thioredoxin (Trx) system, which consists of Trx and thioredoxin reductase (Trr), is not only involved in recycling ...
Methionine sulphoxide reductases revisited: free methionine as a primary target of H2O2 stress in auxotrophic fission yeast

García Santamarina, Sarela, 1978-; Boronat i Llop, Susanna, 1965-; Ayté del Olmo, José; Hidalgo Hernando, Elena (Wiley-Blackwell, 2013)

Amino acid methionine can suffer reversible oxidation to sulphoxide and further irreversible over-oxidation to methionine sulphone. As part of the cellular antioxidant scavenging activities are the methionine sulphoxide ...
