There will be no curiosity, no enjoyment of the process of life. All competing pleasures will be destroyed. But always — do not forget this, Winston — always there will be the intoxication of power, constantly increasing and constantly growing subtler. Always, at every moment, there will be the thrill of victory, the sensation of trampling on an enemy who is helpless. If you want a picture of the future, imagine a boot stamping on a human face — forever.

Since similar sets were already collected for Task 2, the information was reused. In addition searches with HHpred on pdb70 and COMA on pdb40. If two structures were mapped to the same Uniprot entry, only one, the 'most native' one, was used.
None of the searches revealed any structure with >80% sequence identity, other than the two already known structures 2gjx and 2gk1 which share 100% sequence identity. To still perform the task, 2gjx, which is the native structure <ref name="2gjxref">Lemieux,M. et al. (2006) Crystallographic Structure of Human beta-Hexosaminidase A: Interpretation of Tay-Sachs Mutations and Loss of GM2 Ganglioside Hydrolysis. Journal of molecular biology, 359, 913-29.</ref>, was chosen as reference and 2gk1, which has the inhibitor NGT bound, will be used as template.
