General description

β-Glucuronidase Type H-2 from Helix pomatia is a crude solution of enzymes derived from the Roman snail. Many β-glucuronidases derived from mollusks also contain sulfatase activity.

Application

β-Glucuronidase from Helix pomatia has been used:
  • to convert isoflavone conjugates to their aglycone forms in urine and soymilk samples for high performance liquid chromatography (HPLC) detection
  • as a component in the protoplasting solution
  • for the generation of aromatic and phenolic compounds from the plasma and urine samples for gas chromatography-mass spectrometry (GC-MS)
  • to hydrolyze glucuronide and sulfate conjugated metabolites in fecal samples

β-glucuronidase was used in the measurement of aromatization by a urine technique suitable for the evaluation of aromatase inhibitors in vivo.

Más información
sobre los datos de aplicación recientes generados por Sigma I+D para optimizar la hidrólisis de diferentes clases de fármacos utilizando enzimas de diferentes procedencias y el uso de una enzima cromatográficamente purificada para reducir el efecto de la actividad esterasa que tiene como consecuencia la conversión del 6-MAM en morfina

Biochem/physiol Actions

Utilizada para la hidrólisis de conjugados de glucurónido en el análisis de los metabolitos urinarios
β-glucuronidase (β-GIc) is an exoglycosidase that catalyzes the breakdown of complex carbohydrates. In humans it converts conjugated bilirubin into the unconjugated form, making bilirubin suitable for reabsorption.

Quality

Muchas β-glucuronidasas derivadas de los moluscos contienen también actividad sulfatasa.

Unit Definition

Definición de unidad sulfatasa: Una unidad de sulfatasa hidrolizará 1,0 μmol de sulfato de p-nitrocatecol por hora a un pH de 5,0 a 37 °C.
Una unidad Sigma o Fishman modificada liberará 1,0 μg de fenolftaleína del glucurónido de fenolftaleína por hora a 37 °C a un pH de 5,0 (análisis, 30 minutos).
