==CALMODULIN, NMR, 30 STRUCTURES==

The solution structure of Ca(2+)-free calmodulin has been determined by, NMR spectroscopy, and is compared to the previously reported structure of, the Ca(2+)-saturated form. The removal of Ca2+ causes the interhelical, angles of four EF-hand motifs to increase by 36 degrees-44 degrees. This, leads to major changes in surface properties, including the closure of the, deep hydrophobic cavity essential for target protein recognition., Concerted movements of helices A and D with respect to B and C, and of, helices E and H with respect to F and G are likely responsible for the, cooperative Ca(2+)-binding property observed between two adjacent EF-hand, sites in the amino- and carboxy-terminal domains.

== Function ==
 +
[https://www.uniprot.org/uniprot/CALM1_XENLA CALM1_XENLA] Calmodulin mediates the control of a large number of enzymes, ion channels and other proteins by Ca(2+). Among the enzymes to be stimulated by the calmodulin-Ca(2+) complex are a number of protein kinases and phosphatases.

The solution structure of Ca(2+)-free calmodulin has been determined by NMR spectroscopy, and is compared to the previously reported structure of the Ca(2+)-saturated form. The removal of Ca2+ causes the interhelical angles of four EF-hand motifs to increase by 36 degrees-44 degrees. This leads to major changes in surface properties, including the closure of the deep hydrophobic cavity essential for target protein recognition. Concerted movements of helices A and D with respect to B and C, and of helices E and H with respect to F and G are likely responsible for the cooperative Ca(2+)-binding property observed between two adjacent EF-hand sites in the amino- and carboxy-terminal domains.
