title: Crystallization and preliminary X-ray diffraction studies of beta-cryptogein, a toxic elicitin secreted by the phytopathogenic fungus Phytophthora cryptogea.
abstract: Crystals of the basic elicitin secreted by Phytophthora cryptogea have been obtained by the hanging-drop method of vapor diffusion from sodium chloride solutions. The crystals belong to the tetragonal space group P4(1)22 (or enantiomorph P4(3)22), with unit cell dimensions a = b = 47 A, c = 137 A and probably contain two molecules per asymmetric unit. The crystals are very stable to X-rays and diffract to 2.2 A resolution on a synchrotron radiation source.
