Crystallization and preliminary X-ray diffraction analysis of three myotoxic phospholipases A₂ from Bothrops brazili venom

Two myotoxic and noncatalytic Lys49-phospholipases A₂ (braziliantoxin-II and MT-II) and a myotoxic and catalytic phospholipase A₂ (braziliantoxin-III) from B. brazili were crystallized. X-ray diffraction data sets were collected and molecular-replacement solutions were obtained.
