Structural comparison of apo NanICD, NanICD–Neu5Ac and NanICD–diplacone. (a) Overall superposed structures of apo NanICD (orange) and the NanICD–Neu5Ac (cyan) and NanICD–diplacone (yellow) complexes. (b) Catalytic site. Diplacone and Neu5Ac molecules are displayed as green and cyan sticks, respectively. Water molecules (W1, W2 and W3) are shown as red spheres. |
