Crystals and crystal packing of the Tako and Ika proteins. (a) Pictures of the crystals grown under different conditions. (b) Protein structures in the asymmetric unit, with each chain coloured blue to red from the N-terminus to the C-terminus. (c) Two orthogonal views of the crystal packing. The tetragonal Tako8 crystals form a rhomboid cavity of about 40 Å across. The Ika8 and Ika4 crystals show large open channels of about 90 Å across with a honeycomb-like arrangement.
