[Calculation of the quaternary structure of the alpha--beta-dimer of hemoglobin]

The calculation of the structure of haemoglobin alpha--beta-dimer is performed. Calculation is divided into two steps: at the first step highly hydrophobic regions of the subunit surfaces which can provide the stability of the complex are found; at the second--the fitting of this surface regions is carried out. The calculation has resulted in finding three most stable structures. R. m. s. deviation of the positions of C beta-atoms of one of these structures from those in the native one is 3.5 A.
