Molecular Characterization of Copper and Cadmium Resistance Determinants in the Biomining Thermoacidophilic Archaeon Sulfolobus metallicus

Figure 3

Comparison of selected proteins of S. metallicus cells treated with Cu or Cd. Protein extracts were obtained from cells treated without metals and with 100 mM Cu or 1 mM Cd for 24 h and the proteins were separated by 2D-PAGE. The segments (a), (b), and (c) are the enlarged dashed boxes in Figure 2 under the three conditions indicated. Numbers show some of the spots with increased intensity in cells treated with Cu or Cd.
