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 ...
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 ...
Reversible cysteine oxidation in hydrogen peroxide sensing and signal transduction

García Santamarina, Sarela, 1978-; Boronat i Llop, Susanna, 1965-; Hidalgo Hernando, Elena (American Chemical Society, 2014)

Activation of redox cascades through hydrogen peroxide-mediated reversible cysteine oxidation is a major mechanism for intracellular signaling. Understanding why some cysteine residues are specifically oxidized, in competition ...
