Principal amino acids in the DPG binding pocket at the interface between the two beta subunits (β1 and β2). (A) Native hemoglobin with a lysine at position 82. (B) Hemoglobin Providence(asp) with an aspartate at position 82. The positions of the amino acids in β-globin are indicated; the designations in parentheses are helical structure designations. The interface between the two β subunits is indicated by a dashed diagonal line.
