THE STRUCTURE OF HOLO TYPE HUMAN CU, ZN SUPEROXIDE DISMUTASE
OverviewOverview
Cu, Zn superoxide dismutase (SOD1) forms a crucial component of the, cellular defence against oxidative stress. Zn-deficient wild-type and, mutant human SOD1 have been implicated in the disease familial amyotrophic, lateral sclerosis (FALS). We present here the crystal structures of holo, and metal-deficient (apo) wild-type protein at 1.8A resolution. The P21, wild-type holo enzyme structure has nine independently refined dimers and, these combine to form a "trimer of dimers" packing motif in each, asymmetric unit. There is no significant asymmetry between the monomers in, these dimers, in contrast to the subunit structures of the FALS G37R, mutant of human SOD1 and in bovine Cu,Zn SOD. Metal-deficient apo SOD1, crystallizes with two dimers in the asymmetric unit and shows changes in, the ... [(full description)]
