Figure 1. Structure of endoNF (residues 245 -911). (a) Ribbon
diagram of one of the endoNF homotrimers present in the
asymmetric unit. The three monomers are red, blue and yellow.
(b) Structure of the endoNF monomer with its three domains. The
chain is colored from blue at the N terminus to red at the C
terminus. (c) Bottom view of the homotrimer with cross-section
through its triangular tail domain. An 2,8-linked
sialic acid dimer bound to the yellow -barrel
domain is in stick representation.
