Model of Ccs copper acquisition from Ctr1 and complex disassembly by Sod1 maturation. Ctr1 (purple) transports copper (yellow) into the cytosol. Ccs (blue) scans the membrane and associates with the copper-bound Ctr1 C-terminal domain. Sod1 (green) interacts with the Cu(I)-Ctr1-Ccs complex. Sod1 maturation terminates the ternary complex. Ccs is allowed to cycle through the copper-acquisition process again. The Sod1 homo-dimer is fully active. (Color figure online)
