Abstract

Fernanda Canduri, Lit C. Mancuso, Andreimar M. Soares, Jose R. Giglio, Richard J. Ward and Raghuvir K. Arni. Crystallization of piratoxin I, a myotoxic Lys49-phospholipase A(2) homologue isolated from the venom of Bothrops pirajai. Toxicon 36, 547-551, 1998.-Large single crystals of piratoxin I, a Lys49-PLA(2) 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-raps to a resolution of 2.8 Angstrom. Preliminary analysis reveals the presence of two molecules in the crystallographic asymmetric unit. (C) 1998 Elsevier B.V. Ltd. All rights reserved.
