CBM9_1 is a C-terminal domain on bacterial xylanase proteins, and it is tandemly repeated in a number of family-members. The CBM9 module binds to amorphous and crystalline cellulose and a range of soluble di- and monosaccharides as well as to cello- and xylo- oligomers of different degrees of polymerisation. Comparison of the glucose and cellobiose complexes during crystallisation reveals surprising differences in binding of these two substrates by CBM9-2. Cellobiose was found to bind in a distinct orientation from glucose, while still maintaining optimal stacking and electrostatic interactions with the reducing end sugar [1].
