Purification and partial characterization of rat liver bilirubin glucuronoside glucuronosyltransferase.
Bilirubin glucuronoside glucuronosyltransferase (EC 2.4.1.95) converts bilirubin monoglucuronide to bilirubin diglucuronide and is concentrated in plasma membrane-enriched fractions of rat liver homogenates. The enzyme was purified 2,000-fold to homogeneity from rat liver. The pI of the enzyme is 7.9 +/- 0.2. The enzyme has a molecular weight of 160,000 and is an oligomer of 28,000 dalton subun...

متن کاملHepatic conversion of bilirubin monoglucuronide to diglucuronide in uridine diphosphate-glucuronyl transferase-deficient man and rat by bilirubin glucuronoside glucuronosyltransferase.
The microsomal enzyme uridine diphosphate (UDP) glucuronate glucuronyltransferase (E.C. 2.4.1.17) catalyzes formation of bilirubin mono-glucuronide from bilirubin and UDPglucuronic acid. Bilirubin glucuronoside glucuronosyltransferase (E.C. 2.4.1.95), an enzyme concentrated in plasma membrane-enriched fractions of rat liver, converts bilirubin monoglucuronide to bilirubin diglucuronide. Bilirub...
متن کاملPurification and Partial Characterization of Rat Liver Lipoxygenase
Lipoxygenase, Enzyme Purification, Hydrophobic Chromatography Lipoxygenase was purified from rat liver cytosolic fraction by a method involving two successive chromatographic steps on Sephacryl S-200 and Phenyl Sepharose CL-4B. The enzyme has a molecular weight of 96 Kdal and it seems to be composed of two identical subunits. Chromatofocusing of the enzyme revealed a single band of activity at ...
متن کاملPurification and properties of microsomal UDP-glucuronosyltransferase from rat liver.
p-Nitrophenol conjugating activity associated with liver microsomal UDP-glucuronosyltransferase (EC 2.4.1.17) was purified 150- to 200-fold from cell-free homogenates. The purification scheme included solubilization with the nonionic detergent Lubrol WX, anion exchange chromatography at pH 6.0 and 7.5, and affinity chromatography with UDP-hexanolamine Sepharose 4B. The enzyme purified as a phos...
