Abstract excerpt
Extracellular superoxide dismutase (SOD3), a secretory copper enzyme, plays an important role in atherosclerosis and hypertension by modulating the levels of extracellular superoxide anion (O2*-) in the vasculature. Little is known about the mechanisms by which SOD3 obtains its catalytic copper cofactor. Menkes ATPase (MNK) has been shown to transport cytosolic copper to the secretory pathway in nonvascular...
