Measurement of structural and free energy changes in hemoglobin by hydrogen exchange methods

Author: Englander, S.W.

Description: Porphyrins are very generally found in the company of proteins, and a lot of effort has been devoted to finding out how they interact. Many studies have focused on three-dimensional structure and change in three-dimensional structure. Such studies have supplied important parts of the picture; but also fundamental in these interactions are the energy relationships, and about these we know very little … The functional impact of any structure change, its contribution to allosteric signal transmission and to modification of protein function, can only be ascertained by measuring quantitatively its free energy content
