<strong>Protein</strong> <strong>dynamics</strong>: proteins are NOT<br />

static<br />

‣ X-ray <strong>structure</strong>s can be<br />

misleading:<br />

‣ appear static<br />

‣ subject to crystal-lattice lattice<br />

artifacts<br />

NMR PDB files often contain<br />

many <strong>structure</strong>s<br />

consistent with data<br />

1AK8.pdb (calcium-bound calmodulin)<br />

1AK8.pdb (calcium bound calmodulin)<br />

Note local fluctuations – e.g., helixfraying
