<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 />

Note local fluctuations – e.g., helixfraying
