title: Crystallization of piratoxin I, a myotoxic Lys49-phospholipase A2 homologue isolated from the venom of Bothrops pirajai.
abstract: Large single crystals of piratoxin I. a Lys49-PLA2 homologue with low enzymatic activity, have been obtained. The crystals belong to the orthorhombic system space group P2(1)2(1)2(1), and diffract X-rays to a resolution of 2.8 A. Preliminary analysis reveals the presence of two molecules in the crystallographic asymmetric unit.
