  • Title: Crystallization and preliminary X-ray diffraction studies of methemoglobin Bart's.
    Author: Czerwinski EW, Risk M, Matustik MC.
    Journal: J Biol Chem; 1981 Dec 25; 256(24):13128-9. PubMed ID: 6895518.
    Abstract:
    Methemoglobin Bart's (gamma 4) purified from the blood of an alpha thalassemic neonate has been crystallized in a crystal form unique for hemoglobins. The space group is trigonal, P3121, or the enantiomorph P3221, a = b = 55.85 A, c = 159.10 A. There are three tetrameric molecules in the unit cell with two gamma-chains per asymmetric unit.
