functional studies of six abnormal hemoglobins , four at the beta 101 residue in the central cavity near the alpha 1 beta 2 interfce , one near the dpg binding site and one at the c-terminus of the beta chain , indicate that the exact explanation of the structure-function relationship in hemoglobin depends upon the specific residue that is altered and the chemical properties of the substituted group .
