6316150-1	1983	Copper, zinc superoxide dismutase (SOD) catalyses the very rapid two-step dismutation of the toxic superoxide radical (O-2) to molecular oxygen and hydrogen peroxide through the alternate reduction and oxidation of the active-site copper.	Superoxides	99-117	immunoglobulin kappa variable 1D-39	Homo sapiens	119-122	
6316150-3	1983	There is a single, highly complementary position for O-2 to bind to both the Cu(II) and activity-important Arg 141 with correct geometry; two water molecules form a ghost of the superoxide in this position.	Superoxides	178-188	immunoglobulin kappa variable 1D-39	Homo sapiens	53-56
