Using 1H-15N HSQC NMR spectroscopy, we have analyzed hydrogen exchange at the amide groups of wild-type (wt) CuZnSOD and the fALS-associated G93A SOD variant in their fully metalated states.
Dynamic properties of the G93A mutant of copper-zinc superoxide dismutase as detected by NMR spectroscopy: implications for the pathology of familial amyotrophic lateral sclerosis.
Protein expression in HEK293T cells was applied to recapitulate the maturation steps of intracellular superoxide dismutase 1 (SOD1) and to study the effect of mutations linked to familial amyotrophic lateral sclerosis (fALS) by in-cell NMR.
