Proposed Article Title: Copper Zinc Superoxide Dismutase (SOD)

The important function of Cu/ Zn superoxide dismutase (SOD) is to detoxify damaging forms of oxygen. It catalyzes the dismutation of superoxide (O2-) anion into molecular oxygen (O2) and hydrogen peroxide (H2O2)[1]. Mutations or disruptions in the protein can exacerbate a number of diseases, such as amyotrophic lateral sclerosis (ALS) and diabetes[2]. One of the reported mutations involves the reduction of the disulfide bond (show reduced disulfide bond reduction), leading to a destabilized protein structure [2]. This mutation is featured in the fatal ALS disease. The motor neurons of individuals are affected, and voluntary muscle control is lost.
