In contrast to the above theoretical models, multiple conformations can be empirically determined by [[NMR|solution nuclear magnetic resonance]]. These differences between these models may represent either thermal motion, or a lack of sufficient data to restrain the model. An example is | In contrast to the above theoretical models, multiple conformations can be empirically determined by [[NMR|solution nuclear magnetic resonance]]. These differences between these models may represent either thermal motion, or a lack of sufficient data to restrain the model. An example is [[2fxy]], an 18-residue peptide for which 15 models were deposited. | ||

Raul E. Cachau kindly contributed this molecular dynamics simulation of a peptide alpha helix, which he calculated ca. 1995. Permission was given for public display and redistribution, provided the author is credited. The file is in XYZ format, and contains 100 models. Each model contains 75 atoms. Hydrogens are missing except for those on the main chain nitrogens. The file is [[Image:Cachau-peptide-MD-simulation-ca1995.xyz.gz]]. | Raul E.
