2RRT - PubMed Abstract: 
Calmodulin (CaM) is a Ca(2+)-binding protein that functions as a ubiquitous Ca(2+)-signaling molecule, through conformational changes from the "closed" apo conformation to the "open" Ca(2+)-bound conformation. Mg(2+) also binds to CaM and stabilizes its folded structure, but the NMR signals are broadened by slow conformational fluctuations ...
