Abstract

The interaction between the structural conformations occurring at different levels of the protein organization is of key importance in understanding the dynamics of the biological molecules. Hemoglobin is studied here because it provides a good system to investigate fundamental aspects of biomolecules. In hemoglobin we can distinguish three levels of the protein organization 1) the quaternary structure of the tetramer, 2) the tertiary structure of the subunits, 3) the local structure of the Fe site in the heme.
