Figure 4.
Crystal structure of codakine complexed with nona-Asn. A,
representation of the final maximum likelihood weighted 2 mF[o]
- DF[o] electron density map (contoured at 1.0σ, 0.34 e
Å^-3 for the nona-Asn oligosaccharide. B, hydrogen bond
network between oligosaccharide and codakine amino acids.
Intramolecular hydrogen bonds of the nonasaccharide are
represented by blue dashed lines. C, comparison of
oligosaccharide binding site in codakine (left) and DC-SIGN
(right) (43). The star indicates the position of the calcium
ion. Electrostatic surface was calculated with APBS (56).
