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

β-Glucuronidase (GUSB) is a lysosomal enzyme, that degrades glucuronate-containing glycosaminoglycans. β-glucuronidase, obtained from abalone has the ability to hydrolyze samples, that has high analyte concentrations. Absence of β-glucuronidase results in mucopolysaccharidosis type VII (MPSVII), which leads to lysosomal storage in the brain.

Other Notes

One Sigma or modified Fishman unit will liberate 1.0 μg of phenolphthalein from phenolphthalein glucuronide per hr at 37 °C at pH 3.8 (30 min assay).

Physical form

Supplied as an aqueous solution containing L-proline, ammonium acetate and sodium azide
