So this is the enzyme that basically locates and converts superoxide radical species like the one basically discussed right here. So this is the general reaction that basically is catalyzed by super oxide, this mutase. But as we'll see in just a moment, the superoxide, this mutate that is used by ourselves basically carries out a two step process. But this is the general process. So we essentially take two of these superoxide anions. We use two H plus ions.
