Abstact

The crystal structure of deoxyhemoglobin S has been refined at 3.0-A resolution using the Hendrickson-Konnert restrained least-squares method. Comparison with the structure of deoxyhemoglobin A reveals a hingelike movement of the beta-chain A helices, which are involved in molecular contacts, toward the EF corners of their respective subunits. This movement brings the amino termini of the beta-chains closer to the molecular dyad. The A helices remain alpha-helical throughout their entire lengths. No other major structural difference is found between deoxyhemoglobin A and deoxyhemoglobin S.
