Figure 6. Stereoview of xylotriose docking model in
subdomain b of XBD. The xylotriose structure was built based on
the X-ray structure of b-1,4-xylan hydrate [Neduszynski and
Marchessault 1972] and fitted into the binding site manually.
Sugars are numbered from the non-reducing end. XBD residues
interact with the 2nd xylose sugar through five hydrogen bonds
(broken lines). The 2nd and 3rd sugar rings are placed over the
aromatic rings of Tyr380 and Trp383.
