Bacterial alpha-L-rhamnosidase 6 hairpin glycosidase 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.

Alpha-L-rhamnosidase N-terminal domain. This family consists of bacterial rhamnosidase A and B enzymes. This domain is probably involved in substrate recognition.

Bacterial alpha-L-rhamnosidase concanavalin-like 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.

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.

FIVAR domain. This domain is found in a wide variety of contexts, but mostly occurring in cell wall associated proteins. A lack of conserved catalytic residues suggests that it is a binding domain. From context, possible substrates are hyaluronate or fibronectin (personal obs: C Yeats). This is further evidenced by. Possibly the exact substrate is N-acetyl glucosamine. Finding it in the same protein as pfam05089 further supports this proposal. It is found in the C-terminal part of Bacillus sp. Gellan lyase, which is removed during maturation. Some of the proteins it is found in are involved in methicillin resistance. The name FIVAR derives from Found In Various Architectures.
