[[http://www.uniprot.org/uniprot/SODC_HUMAN SODC_HUMAN]] Defects in SOD1 are the cause of amyotrophic lateral sclerosis type 1 (ALS1) [MIM:[http://omim.org/entry/105400 105400]]. ALS1 is a familial form of amyotrophic lateral sclerosis, a neurodegenerative disorder affecting upper and lower motor neurons and resulting in fatal paralysis. Sensory abnormalities are absent. Death usually occurs within 2 to 5 years. The etiology of amyotrophic lateral sclerosis is likely to be multifactorial, involving both genetic and environmental factors. The disease is inherited in 5-10% of cases leading to familial forms.<ref>PMID:12963370</ref><ref>PMID:19741096</ref><ref>PMID:8528216</ref><ref>PMID:8682505</ref><ref>PMID:9541385</ref><ref>PMID:12754496</ref><ref>PMID:15056757</ref><ref>PMID:18378676</ref>[:]<ref>PMID:8446170</ref><ref>PMID:8351519</ref><ref>PMID:8179602</ref><ref>PMID:7980516</ref><ref>PMID:8069312</ref><ref>PMID:7951252</ref><ref>PMID:7881433</ref><ref>PMID:7836951</ref><ref>PMID:7997024</ref><ref>PMID:7870076</ref><ref>PMID:7887412</ref><ref>PMID:7795609</ref><ref>PMID:7655468</ref><ref>PMID:7655469</ref><ref>PMID:7655471</ref><ref>PMID:7700376</ref><ref>PMID:7647793</ref><ref>PMID:7501156</ref><ref>PMID:7496169</ref><ref>PMID:8938700</ref><ref>PMID:8907321</ref><ref>PMID:8990014</ref><ref>PMID:9101297</ref><ref>PMID:9455977</ref><ref>PMID:10732812</ref><ref>PMID:9131652</ref><ref>PMID:10400992</ref><ref>PMID:10430435</ref><ref>PMID:11535232</ref><ref>PMID:11369193</ref><ref>PMID:12402272</ref><ref>PMID:12145308</ref><ref>PMID:14506936</ref><ref>PMID:18552350</ref><ref>PMID:18301754</ref><ref>PMID:21247266</ref><ref>PMID:21220647</ref> | <tr><td class="sblockLbl"><b>[[Non-Standard_Residue|NonStd Res:]]</b></td><td class="sblockDat"><scene name='pdbligand=ACE:ACETYL+GROUP'>ACE</scene></td></tr> | ||

== Publication Abstract from PubMed == | |||
Superoxide dismutase enzymes protect aerobic organisms from oxygen-mediated free-radical damage. Crystallographic structures of recombinant human Cu,Zn superoxide dismutase have been determined, refined, and analyzed at 2.5 A resolution for wild-type and a designed thermostable double-mutant enzyme (Cys-6----Ala, Cys-111----Ser). The 10 subunits (five dimers) in the crystallographic asymmetric unit form an unusual stable open lattice with 80-A-diameter channels. The 10 independently fit and refined subunits provide high accuracy, error analysis, and insights on loop conformations. There is a helix dipole interaction with the Zn site, and 14 residues form two or more structurally conserved side-chain to main-chain hydrogen bonds that appear critical to active-site architecture, loop conformation, and the increased stability resulting from the Cys-111----Ser mutation. | |||
