In the mutant hemoglobin known as HB Providence, an asparagine residue in the B-chain replaces Lys-82. In the normal hemoglobin, Lys-82 projects in the cental cavity of the hemoglobin molecule. Predict the effect of the Lys-Asn mutation of the affinity of allosteric modifiers (relative to normal Hb e.g HbA) and describe the effect the mutation would have on the function (oxygen binding) og HB Providence.
