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.

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 3.8 (30 min assay).

Physical form

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