The a-helical region is now clearly defined, and there are also regions of b-structure.

The structure shown has four <scene name='User:Michael_Roberts/BIOL115_CaM/Structure_plus_c/3'>Ca2+ ions</scene> bound. In this condition, the protein adopts the extended structure shown. The EF hand-forming helices are bent away from the long linking helix, revealing hydrophobic residues and exposing the linking chain.

'''CO-ORDINATING RESIDUES''': To illustrate how Ca2+  is bound, this display shows the <scene name='User:Michael_Roberts/BIOL115_CaM/Co-ordination/1'>residues </scene>that take part in binding one of the Ca2+ ions.


 
<scene name='User:Michael_Roberts/BIOL115_CaM/Co-ordination/2'>'''ZOOM'''</scene> to see this more clearly.  
 
 
 
Let us color the two main forms of regular <scene name='Sandbox_LUBIOL115/Structure_plus_ca/1'>secondary structure</scene> in this protein. Alpha helix appears in red, beta sheet in yellow.
