Figure 4. Demetallization-induced structural changes on
apo-PAL. (a) Stereo view of the superposition of holo-PAL (chain
B from pdb entry 1ukg) on apo-PAL (chain B). The metal binding
loop is coloured cyan for holo-PAL and blue for apo-PAL. (b)
Stereo view of the superposition of the metal binding loop of
holo-PAL (grey) on apo-PAL (in blue). Calcium ions are shown as
yellow spheres and manganese ions as green spheres.
