title: Preliminary X-ray analysis of crystals of fasciculin 1, a potent acetylcholinesterase inhibitor from green mamba venom.
abstract: Fasciculin 1 from Dendroaspis angusticeps has been crystallized by vapour diffusion, in sodium acetate using sodium thiocyanate as precipitant. Tetragonal crystals (space group P4(1)2(1)2 or P4(3)2(1)2) diffract to 1.8 A resolution. The unit cell parameters are a = 40.4 A and c = 81.1 A. We estimated the presence of one molecule in the asymmetric unit.
