== Publication Abstract from PubMed ==
Alpha-insect scorpion toxins are a distinct group of scorpion neurotoxins for which no crystal structures are yet available. A novel alpha-insect toxin named BmKalphaIT1 from the scorpion Buthus martensii Karsch (BmK) has been expressed as an inclusion body in Escherichia coli and purified by chromatography after renaturation. Recombinant BmKalphaIT1 (rBmKaIT1) was crystallized using the vapour-diffusion technique in hanging drops at 296 K. The crystals, which were grown in sodium phosphate, belonged to the orthorhombic space group P2(1)2(1)2(1), with unit-cell parameters a = 30.24 (1), b = 36.51 (3), c = 57.08 (2) A. Diffraction data were collected to 2.1 A resolution using synchrotron radiation. There appears to be one rBmKalphaIT1 molecule in the asymmetric unit.
