Figure 2. Comparison of the structures of Rubisco-Ca^2+-2CABP (C atoms coloured yellow) and Rubisco-Ca^2+-RuBP (C atoms coloured green) in the region around loop 6 of the a/b-barrel. In the Rubisco-Ca^2+-RuBP complex, loop 6 is retracted from the active site and Lys334 makes no interactions with the substrate.
