Specific extraction method requires to be applied, check as published in Page et al. (2012).MnSOD3 can be only detected in Fe-limited cells (0.5 or 0.2 mM added Fe) (i.e., samples exhibiting the novel MnSOD activity) but not in cells grown with higher concentrations of added Fe.
MnSOD3(superoxide dismutase) is a chloroplast enzyme that destroys free radicals produced within cells, which are toxic to biological systems. Page et al.(2012) showed that it is induced under Fe restriction, Mn deficiency and H2O2 stress.
