Glycosaminoglycan (GAG) polysaccharide lyase family. This family consists of a group of secreted bacterial lyase enzymes capable of acting on glycosaminoglycans, such as hyaluronan and chondroitin, in the extracellular matrix of host tissues, contributing to the invasive capacity of the pathogen. These are broad-specificity glycosaminoglycan lyases which recognize uronyl residues in polysaccharides and cleave their glycosidic bonds via a beta-elimination reaction to form a double bond between C-4 and C-5 of the non-reducing terminal uronyl residues of released products. Substrates include chondroitin, chondroitin 4-sulfate, chondroitin 6-sulfate, and hyaluronic acid. Family members include chondroitin AC lyase, chondroitin abc lyase, xanthan lyase, and hyalurate lyase.

Polysaccharide lyase family 8, super-sandwich domain. This family consists of a group of secreted bacterial lyase enzymes EC:4.2.2.1 capable of acting on hyaluronan and chondroitin in the extracellular matrix of host tissues, contributing to the invasive capacity of the pathogen.

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.

Polysaccharide lyase family 8, N terminal alpha-helical domain. This family consists of a group of secreted bacterial lyase enzymes EC:4.2.2.1 capable of acting on hyaluronan and chondroitin in the extracellular matrix of host tissues, contributing to the invasive capacity of the pathogen.
