일반 설명
β-Glucuronidase Type H-2 from Helix pomatia is a crude solution of enzymes derived from the digestive juices of the Roman snail. β-glucuronidases derived from mollusks often contain sulfatase activity. Both activities are useful in the hydrolysis of metabolites for toxicology and biomarker analysis. For a broader look at our β-Glucuronidase product line and their uses see our page about Drug Metabolite Analysis

생화학적/생리학적 작용
Endogenous beta-glucuronidase is a lysosomal enzyme involved in digestion of glucuronide-modified catabolites.
Microbial beta-glucuronidase found in microbiota can cause re-absorption of metabolites by hydrolysis of glucuronide conjugates of xenobiotic and endobiotic metabolites.
