Figure 1
(a) and (b) Orthogonal views of the M. viridifaciens sialidase. The catalytic domain (47–403) is in light brown with Neu5Ac2en bound in the active site, the immunoglobulin-like domain (403–505) is in green and the CBM (505–647) is in cyan with lactose bound. The metal ion is shown as a magenta ball. The disulfide between 351–405 linking the first two domains is also shown. (c) Molecular surface coloured according to electrostatic potential; same view as in (a).
