Domain of unknown function (DUF4838). This family consists of several uncharacterized proteins found in various Bacteroides and Chloroflexus species. The function of this family is unknown.
DOMON-like type 9 carbohydrate binding module. 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. CBM9 domains found in this uncharacterized subfamily are typically found at the N-terminus of longer proteins that lack additional annotation with domain footprints.
