Crystallization and preliminary X-ray diffraction studies of haemorrhagin I from the snake venom of Agkistrodon acutus.
Haemorrhagin I from the snake venom of Agkistrodon acutus (AaHI) has been crystallized using the hanging-drop vapour diffusion method. The crystals belong to space group P4(1)2(1)2 or P4(3)2(1)2 with unit-cell dimensions a = b = 63.61 and c = 95.69 A. There is one molecule in the asymmetric unit. Data to 2.35 A resolution have been collected using a single-crystal.
