SOD-like activity and (a) iron content. (b) S/Fe ratio and (c) P/Fe ratio of ferritins from different organisms; data are presented as mean ± SD (n = 3 independent experiments). d Scheme of the synthesis process of ferritin with reconstituted iron core. e, f The SOD-like activity of the reconstituted, biomineralized ferritins and ferritins purified from the basic medium (-Fe). g The SOD-like activity of the pfFn reconstituted with gradient phosphate/iron ratios (Pi/Fe); data in e–g are presented as mean ± SD (n = 3 independent experiments); the significant difference was evaluated by the Two-way ANOVA with post-hoc Tukey HSD test; ns: not significant, p > 0.05. Source data are provided as a Source Data file.
