Crystallographic characterization of tetanus toxin fragment C

Abstract

The C-terminal fragment from tetanus toxin has been crystallized. The 50 kDa protein forms prismatic crystals with an orthorhombic unit cell of dimension a =64·03 Å, b=76·31 Å and c =135·3 Å. The space group is P 212121. Assuming one molecule per asymmetric unit, the solvent occupies 63% of the unit cell.
