General annotation (Comments)

Function	Protect the extracellular space from toxic effect of reactive oxygen intermediates by converting superoxide radicals into hydrogen peroxide and oxygen.
Catalytic activity	2 superoxide + 2 H⁺ = O₂ + H₂O₂.
Cofactor	Binds 1 copper ion per subunit By similarity. Binds 1 zinc ion per subunit By similarity.
Subunit structure	Homotetramer.
Subcellular location	Secreted › extracellular space. Note: 99% of EC-SOD is anchored to heparan sulfate proteoglycans in the tissue interstitium, and 1% is located in the vasculature in equilibrium between the plasma and the endothelium.
Tissue specificity	Expressed in blood vessels, heart, lungs, kidney and placenta. Major SOD isoenzyme in extracellular fluids such as plasma, lymph and synovial fluid.
Polymorphism	The variant Gly-231 which is found in about 2.2% of individual displays a 10-fold increased plasma EC-SOD content due to reduced heparin-binding affinity and thus the impairment of its binding ability to endothelial cell surface.
Sequence similarities	Belongs to the Cu-Zn superoxide dismutase family.
