Crystal structure of hemoglobin D from the Aldabra giant tortoise (Geochelone gigantea) at 2.0 A resolution
Overview
Hemoglobin D (Hb D) from the Aldabra giant tortoise, Geochelone gigantea, was crystallized by the hanging drop vapor diffusion technique with a, precipitant solution containing 10% polyethylene glycol 3350 and 50 mM, HEPES-Na, pH 7.5. The Hb D crystals of G. gigantea, which diffract to at, least a 2.0 A resolution, belong to the monoclinic space group C2 with, unit cell dimensions of a = 112.1 A, b = 62.4 A, c = 54.0 A, and beta =, 110.3 degrees. One alphabeta dimer molecule of Hb D existed in an, asymmetric unit, with a calculated value of Vm of 2.77 A(3)Da(-1).
