pH sensitivity of metal uptake by tetrameric apo-MnSODs. Fluorimetric metal binding timecourses were recorded for Co2+ binding to human apo-MnSOD (A) or Thermus thermophilus apo-MnSOD (B) over a range of pH values and the pseudo first-order rate constant was evaluated by regression analysis in Scientist. The fitted lines have slopes (A) 1.8±0.1, and (B) 2.05±0.08.
