CBM64 adsorbs to various beta1-4-linked pyranose substrates showing high affinity for cellulose. We present the first crystal structure of a CBM64 at 1.2 A resolution, which reveals a jelly-roll-like fold corresponding to a surface-binding type A CBM. Modeling of its interaction with cellulose indicates that CBM64 achieves association with the hydrophobic face of beta-linked pyranose chains via a unique coplanar arrangement of four exposed tryptophan side chains.
