摘要
1 Introduction Oxidation and reduction of disulfide have been widely studied owing to its importance in the enzyme kinetics. The electron adduct of disulfide RSSR<sup>.-</sup> has been proved to be a critical intermediate of the disruption of the disulfide bridge that leads to the inactivation of enzymes. However, the transient radicals produced by the radiation oxidation of cystine, such as CySSCy<sup>+</sup>, CySS, can also make inactive enzymes.
