Thermal motion of peptide

Theoretical Model: The protein structure described on this page was determined theoretically, and hence should be interpreted with caution.

This animation shows an early (ca. 1995) molecular dynamics simulation of thermal motion of an 11-residue alpha-helical poly-alanine peptide. Hydrogen atoms are missing in these models, except for hydrogens on the main chain nitrogens.

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 File:Cachau-peptide-MD-simulation-ca1995.xyz.gz.
