CUBIC CRYSTAL STRUCTURE OF NATIVE HORSE SPLEEN FERRITIN
OverviewOverview
Horse-spleen apoferritin is known to crystallize in three different space, groups, cubic F432, tetragonal P42(1)2 and orthorhombic P2(1)2(1)2. A, structure comparison of the cubic and tetragonal forms is presented here., Both crystal forms were obtained by the vapor-diffusion technique and data, were collected at 2.26 A (cubic crystal) and 2.60 A (tetragonal crystal), resolution. Two main differences were observed between these crystal, structures: (i) whereas intermolecular contacts only involve salt-bridge, type interactions via cadmium ions in the cubic structure, two types of, interactions are observed in the tetragonal crystal (cadmium-ion-mediated, salt bridges and hydrogen-bonding interactions) and (ii) cadmium ions, bound in the threefold axes of ferritin molecules exhibit lower, ...
