Abstract

Background: Cu, Zn-superoxide dismutase (SOD1) possesses a highly conserved intramolecular disulfide bond. Results: Structural destabilization of SOD1 scrambles the intramolecular disulfide to form cross-linked oligomers with an intermolecular disulfide bond. Conclusion: Disulfide scrambling is a key to understand the folding/misfolding process of SOD1. Significance: A disulfide-scrambling model provides a molecular pathomechanism describing the formation of disulfide-linked SOD1 oligomers in amyotrophic lateral sclerosis.
