Application


Sample preparation for LC/MS through digestion of glucuronide conjugated compounds for biomarker and toxicology research. Removal of glucuronide conjugates such as for the preparation of Baicalein.­


New Technical Article Comparing Performance of Different EnzymesLearn more about recent application data generated by Sigma R&D to optimize hydrolysis for different drug classes using enzymes from different sources and the use of a chromatographicaly purified enzyme to reduce the effect of esterase activity resulting in conversion of 6-MAM to Morphine


Biochem/physiol Actions


Used for the hydrolysis of glucuronide conjugates in urinary metabolite analysis


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.


Features and Benefits


pH optima 4.0 - 5.0.Sulfatase pH optima 6.2Low Sulfatase activity (﹤7,500 units/mL).Ammonium Sulfate suspension.Mollusk-derived beta-glucuronidase.Useful for acidic hydrolysis of glucuronides in low pH samples.


General description


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.

Linkage


Similar to G0876, but produced by Sigma.


Packaging


25 mL in glass bottle


Physical form


Aqueous solution in ~1.0 M ammonium sulfate with 3 mM sodium azide as preservative.


Quality


Many β-glucuronidases derived from mollusks also contain sulfatase activity.


Unit Definition


One Sigma or modified Fishman unit will liberate 1.0 µg of phenolphthalein from phenolphthalein glucuronide per hr at 37?°C at pH 5.0 (30 min assay).


Sulfatase Unit Definition: One unit of sulfatase will hydrolyze 1.0 µmole p-nitrocatechol sulfate per hr at pH 5.0 at 37?°C.
