Normal binding and reactivity of copper in mutant superoxide dismutase isolated from amyotrophic lateral sclerosis patients.

Abstract excerpt

In some families with amyotrophic lateral sclerosis (ALS), the disease is linked to mutations in the gene encoding CuZn-superoxide dismutase. The mutant CuZn-superoxide dismutases appear to cause motor neuron degeneration by a toxic property, suggested to be linked to an altered reactivity of the active-site Cu ions. Asp90Ala mutant CuZn-superoxide dismutase was isolated from six patients with ALS, allowing...
