DOMON-like type 9 carbohydrate binding module of xylanases. Family 9 carbohydrate-binding modules (CBM9) play a role in the microbial degradation of cellulose and hemicellulose (materials found in plants). The domain has previously been called cellulose-binding domain. The polysaccharide binding sites of CBMs with available 3D structure have been found to be either flat surfaces with interactions formed by predominantly aromatic residues (tryptophan and tyrosine), or extended shallow grooves. The CBM9 domain frequently occurs in tandem repeats; members found in this subfamily typically co-occur with glycosyl hydrolase family 10 domains and are annotated as endo-1,4-beta-xylanases. CBM9 from Thermotoga maritima xylanase 10A is reported to have specificity for polysaccharide reducing ends.

Carbohydrate family 9 binding domain-like. 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 polymerization. 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.

carbohydrate binding module family 86. This family describes what is most likely a xylan-binding module such as found in the Xyn10A protein of Roseburia intestinalis L1-82, which is involved in the extracellular capture and breakdown of xylan.
