Structural comparison of Cp-NanICD, the human Neu2–Neu5Ac2en complex structure and homology models of human Neu1, Neu3 and Neu4. (a) Overall superposed structures of Cp-NanICD (green), the human Neu2–Neu5Ac2en complex structure (grey) and homology models of human Neu1 (purple), Neu3 (brown) and Neu4 (magenta). (b) Detailed view. Diplacone and Neu5Ac2en molecules are displayed as green and grey sticks, respectively. Water molecules are shown as red spheres. |
