In the present study, xanthine oxidase acting on its substrates has been found to initiate the aerobic oxidation of sulfite by free radical chains of great length ...

متن کاملStudies on the reaction of sulfite with proteins.
Structural investigations on proteins frequently require as a first step the cleavage of the disulfide bonds that link half-cystine residues. Oxidation with performic acid has been used for this purpose first by Sanger (2) and later by Hirs (3), before a detailed investigation of the sequences of the amino acid residues in insulin and ribonuclease, two proteins that are devoid of tryptophan. Sp...
