Glycosyl Hydrolase Family 88. Unsaturated glucuronyl hydrolase catalyzes the hydrolytic release of unsaturated glucuronic acids from oligosaccharides (EC:3.2.1.-) produced by the reactions of polysaccharide lyases.

Rhamnogalacturonyl hydrolase YesR [Carbohydrate transport and metabolism].

Domain of unknown function (DUF4832). This family consists of uncharacterized proteins around 200 residues in length and is mainly found in various Bacteroides and Capnocytophaga species. The function of this family is unknown. Distant homology analysis suggests a possible similarity of proteins from this family to TIM barrel glycoside hydrolases and, subsequently its involvement in carbohydrate metabolism.The domain lies downstream of glycosyl hydrolases 42 suggesting that as a domain it might represent the carbohydrate-binding region of the enzyme.

The periplasmic binding component of ABC tansport system specific for an unknown oligosaccharide; possess the type 2 periplasmic binidng fold. This group represents an uncharacterized periplasmic-binding protein of an ATP-binding cassette transporter predicted to be involved in uptake of an unknown oligosaccharide molecule. Members of this group belong to the type 2 periplasmic-binding fold superfamily. PBP2 is comprised of two globular subdomains connected by a flexible hinge and bind their ligand in the cleft between these domains in a manner resembling a Venus flytrap. The majority of PBP2 proteins function in the uptake of small soluble substrates in eubacteria and archaea. After binding their specific ligand with high affinity, they can interact with a cognate membrane transport complex comprised of two integral membrane domains and two cytoplasmically located ATPase domains. This interaction triggers the ligand translocation across the cytoplasmic membrane energized by ATP hydrolysis.
