ProteomicsIdentification of intramolecular disulfide bonds in GrxS12
To investigate whether the conserved Cys residues of Grxs form intramolecular or intermolecular disulfide bonds, the recombinant GrxS12 proteins were purified, and subsequently separated using non-reducing SDS-PAGE. The gel revealed the presence of a monomer band but not a dimer band, indicating the...

Grxs12 Identification Intramolecular disulfide bond 
ProteomicsIntramolecular disulfide bridges in Voltage-Dependent Anion Channel 2 (VDAC2) protein from Rattus norvegicus revealed by high resolution mass spectrometry.
Voltage-Dependent Anion Channel isoforms (VDAC1, VDAC2, VDAC3) are relevant component of the outer mitochondrial membrane and play crucial role in cellular processes, in regulation of metabolism and in survival pathways. Recently, we reported the characterization of the oxidation pattern of cysteine...

ProteomicsA disulfide redox switch mechanism regulates glycoside hydrolase function
Disulfide bond is a key post-translational modification involved in protein folding, stability, and functional regulation. While the structural role of disulfide bonds has been extensively studied in protein chemistry, their potential involvement in regulating catalytic activity of carbohydrate-acti...
