The layout of this reaction may differ from that in the pathway view due to the constraints in pathway layout
A portion of SOD1 is located in the mitochondrial intermembrane space (IMS) where it catalyzes the formation of oxygen (O2) and hydrogen peroxide (H2O2) from superoxide (O2.-) (He et al. 2011, Higgins et al. 2002, inferred from rat in Okado-Matsumoto and Fridovich 2001).
