ReDisulphID

a tool for identifying drug-targetable redox-active disulphides

Glutathione peroxidase 1

Intermolecular
Cysteine 98 and cysteine 98
Intramolecular
Cysteine 78 and cysteine 115
A redox-regulated disulphide may form between two units of Glutathione peroxidase 1 at cysteines 98 and 98 (91 and 91 respectively in this structure). However, the redox score of this cysteine pair is lower than any known redox-active intermolecular disulphide. ?
