b-Glucuronidase has been found in tissue extracts of mammals and other vertebrates, digestive juices of snails, molluscs, locusts, bacteria and plants. The enzyme catalyzes the hydrolysis of b-glucuronides and also the transfer of glucuronly radicals to acceptor alcohols. b-Glucuronidase is a structural protein of the endoplasmic reticulum,. Its occurence in the lysozomes is due to changes in the endoplasmic reticulum. b-Glucuronidase catalyzes the following reaction: b-Glucuronidase b-D-Glucuronide + H2O ---> Alcohol + D-Glucuronate Aryl Sulfatase Activity: As reported Activity: ~2000/mg Protein Extinction Coefficient: 4.08 Unit Definition: 1 unit is equal to the amount of enzyme which liberates 1ug of phenolphthalein from phenolphthalein glucuronide per hour at 37 degrees C, pH 5. Specificity: The enzyme hydrolyzes a large variety of conjugated glucuronides but not alpha-or beta-glucosides. Inhibitors: Strongly, reversibly inhibited by various organic peroxides Application: Suitable for use in urine steroid determinations. Storage and Stability: Lyophilized powder may be stored at -20 degrees C. Stable for 6 months at -20 degrees C. Reconstitute with sterile 2% sodium chloride. Prepare fresh per assay.
