Sulfite oxidase + ('''Sulfite oxidase''' (SO) is a dimeric en … '''Sulfite oxidase''' (SO) is a dimeric enzyme, located in the intermembrane space of mitochondria, with each monomer containing a single Mo cofactor and cyt b5-type heme [1]. SO catalyzes the oxidation of sulfite to sulfate as the terminal step in the metabolism of sulfur amino acids and is vital for human health. Inherited mutations in SO result in severe neurological problems, stunted brain growth, and early death [2]. Function: SO catalyzes the terminal reaction in the oxidative degradation of sulfur amino acids with the formation of a sulfate, electrons pass to cytochrom ''c'' and are further utilized in the respiratory system.Sulfite + O2 + H2O --> Sulfate + H2O2 Localization: The level of expression of SO differs in various tissues with main predominant localization in liver, kidney, skeletal muscle, heart, placenta, and brain in humans and liver, kidney, heart, brain, and lung in rats [3]. Deficiency: SO is vital for metabolic pathways of sulfur amino acids (cysteine and methionine). Complete lack of this enzyme, typically caused by gene mutation, leads to lethal disease called sulfite oxidase deficiency characterized by neurological abnormalities with brain atrophy.ed sulfite oxidase deficiency characterized by neurological abnormalities with brain atrophy.)
