Abstract
The most striking fact in Hb Nouakchott [alpha 114(GH2)Pro----Leu] is the highly increased hydrophobicity of the abnormal chain. In comparison to other variants carrying the same amino-acid substitution, but at another position, the involvement of the environmental domains in the expression of the hydrophobicity is shown. Even though the substitution concerned a proline residue, it was without consequences on the oxygen binding and the stability of the molecule.
