Proteins are one of the major targets for oxidative damage in the cell.Indirect non-radical oxidation of the protein via formation and subsequent reaction with single oxygen (O-1(2))is one of the major processes.In this work we studied the single oxygen(O-1(2))-mediated oxidation of bovine serum albumin (BSA) by constant current chronopotentiometry in combination with mercury electrode.Our chronopotentiometric data show that photo-oxidized BSA was more susceptible to the electric field-induced denaturation than non-oxidized native BSA. Our method utilizing intrinsic electrochemical signal of proteins provides a sensitive detection methods for minor damages in various proteins.
