calbindin D9k	no species information	The conformational change between apo and one magnesium ion bound states involves: One magnesium ion binds to site II. The conformation of the Mg1 state is distinct form the apo or Ca2 state. Helical packing is more compact. In particular, the angle between helix III and IV is ~25 degrees less in the Mg1 state than in the calcium-loaded or apo states.	Melanie R.

calbindin D9k	no species information	The conformational change between apo and one manganese ion bound states involves: One manganese ion binds to site II. The conformation of the Mn1 state is distinct form the apo or Ca2 state, but very similar to the Mg1 state. Helical packing is more compact than in the apo or Ca2 states. In particular, the angle between helix III and IV is ~25 degrees less in the Mn1 state than in the calcium-loaded or apo states.	Melanie R.
