REFINED CRYSTAL STRUCTURE OF DEOXYHEMOGLOBIN S. I. RESTRAINED LEAST-SQUARES REFINEMENT AT 3.0-ANGSTROMS RESOLUTION
Contents |
Overview
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.
