Abstract
An insect-specific toxin from the venom of the scorpion Androctonus australis Hector has been crystallized. The crystals are orthorhombic, space groups P2(1)2(1)2(1), with cell dimensions a = 66.4 A, b = 52.5 A and c = 36.1 A. Calculations based on the unit cell volume and toxin molecular mass suggest that there are two molecules in the asymmetric unit.
摘要
一种来自澳大利亚杀人蝎毒液的昆虫特异性毒素已被结晶。晶体为正交晶系，空间群为P2(1)2(1)2(1)，晶胞参数a = 66.4 Å，b = 52.5 Å，c = 36.1 Å。基于晶胞体积和毒素分子量的计算表明，不对称单元中有两个分子。
