30367882-6	2019	ECSOD, A1AT, and PLTP were observed to be glutathionylated at the functionally important cysteine residues.	Cysteine	89-97	superoxide dismutase 3	Homo sapiens	0-5	
15518578-2	2004	Human EC-SOD contains an additional cysteine residue and folds into two forms with distinct disulfide bridge patterns.	Cysteine	36-44	superoxide dismutase 3	Homo sapiens	6-12	
18385137-9	2008	This study shows that generation of the EC-SOD folding variants is an intracellular event that depends on a free cysteine residue not involved in disulfide bonding.	Cysteine	113-121	superoxide dismutase 3	Homo sapiens	40-46	
14615576-3	2003	Cu/Zn-SOD is a homodimer containing four cysteine residues within each subunit, and EC-SOD is a tetramer composed of two disulfide-bonded dimers in which each subunit contains six cysteines.	Cysteine	180-189	superoxide dismutase 3	Homo sapiens	84-90
