ATOMIC RESOLUTION CRYSTAL STRUCTURE OF HUMAN SUPEROXIDE DISMUTASE

Overview

Mutations of the gene encoding Cu-Zn superoxide dismutase (SOD1) cause 20%, of the familial cases of the progressive neurodegenerative disease ALS. A, growing body of evidence suggests that in familial ALS (FALS) it is the, molecular behavior of the metal-depleted SOD1 dimer that leads to a gain, of toxic properties by misfolding, unfolding, and aggregation. Structural, studies have so far provided static snapshots on the behavior of the, wild-type enzyme and some of the FALS mutants. New approaches are required, to map out the structural trajectories of the molecule. Here, using our, 1.15-A resolution structure of fully metallated human SOD1 and highly, parallelized molecular dynamics code on a high-performance capability, computer, we have undertaken molecular dynamics calculations to ...
