Crystallization and preliminary crystallographic studies of a phospholipase A2 from the venom of the Brazilian snake Bothrops moojeni.
A phospholipase A(2) purified from the venom of the snake Bothrops moojeni has been crystallized by vapour-diffusion techniques in hanging drops at 291 K. The crystals, which were grown in the absence of Ca(2+), belong to the cubic system, space group P432, with unit-cell parameters a = b = c = 91.86 A, and contain one molecule in the asymmetric unit (V(M) = 2.71 A(3) Da(-1)). X-ray diffraction experiments provide data to 2.35 A resolution collected on a rotating-anode home source at cryogenic temperatures. The structure has been solved via molecular-replacement techniques using a single monomer of the crystallographic structure of the phospholipase from the Western diamondback rattlesnake (Crotalus atrox) as a search model.
