Carbohydrate-Binding Module Family 4

Activities in FamilyModules of approx. 150 residues found in bacterial enzymes. Binding of these modules has been demonstrated with xylan, β-1,3-glucan, β-1,3-1,4-glucan, β-1,6-glucan and amorphous cellulose but not with crystalline cellulose.
3D Structure Statusβ-sandwich
NotePreviously known as cellulose-binding domain family IV (CBD IV).
