ReDisulphID

a tool for identifying drug-targetable redox-active disulphides

cGMP-inhibited 3',5'-cyclic phosphodiesterase 3A

Intermolecular
Cysteine 957 and cysteine 957
Intramolecular
Cysteine 942 and cysteine 945
Cysteine 1013 and cysteine 1073
A redox-regulated disulphide may form between two units of cGMP-inhibited 3',5'-cyclic phosphodiesterase 3A at cysteines 957 and 957. However, the redox score of this cysteine pair is lower than any known redox-active intermolecular disulphide. ?
