Beta-glucuronidase

Beta-glucuronidases are members of the glycosidase family of enzymes that catalyze breakdown of complex carbohydrates. Human β-glucuronidase is a type of glucuronidase (a member of glycosidase Family 2) that catalyzes hydrolysis of β-D-glucuronic acid residues from the non-reducing end of mucopolysaccharides (also referred to as glycosaminoglycans) such as heparan sulfate.〔 Human β-glucuronidase is located in the lysosome. In the gut, brush border β-glucuronidase converts conjugated bilirubin to the unconjugated form for reabsorption. Beta-glucuronidase is also present in breast milk, which contributes to neonatal jaundice.
== Structure ==
Human β-glucuronidase is synthesized as an 80 kDa monomer (653 amino acids) before proteolysis removes 18 amino acids from the C-terminal end to form a 78 kDa monomer.
Beta-glucuronidase exists as a 332 kDa homotetramer. Beta-glucuronidase contains several notable structural formations, including a type of beta barrel known as a jelly roll barrel and a TIM barrel.〔
