Figure 6. Ferroxidase activity of recombinant ferritin from Chaetopterus.
Measurements were made in sodium-acetate buffer at pH 6.0 with varying concentration of Fe2+ using affinity-purified recombinant ferritin. Data (mean ± SE, N = 3) were plotted with nonlinear linear models, Michaelis-Menten (dotted line) and Gompertz (black line).
