Bacterial alpha-L-rhamnosidase C-terminal domain. This family consists of bacterial rhamnosidase A and B enzymes. L-Rhamnose is abundant in biomass as a common constituent of glycolipids and glycosides, such as plant pigments, pectic polysaccharides, gums or biosurfactants. Some rhamnosides are important bioactive compounds. For example, terpenyl glycosides, the glycosidic precursor of aromatic terpenoids, act as important flavouring substances in grapes. Other rhamnosides act as cytotoxic rhamnosylated terpenoids, as signal substances in plants or play a role in the antigenicity of pathogenic bacteria.

Domain of Unknown Function (DUF1080). This family has structural similarity to an endo-1,3-1,4-beta glucanase belonging to glycoside hydrolase family 16. However, the structure surrounding the active site differs from that of the endo-1,3-1,4-beta glucanase.
