title: An improved purification procedure for sulfite oxidase from bovine liver.
abstract: Sulfite oxidase (Sulfite:O2 oxidoreductase, EC 1.8.3.1) has been purified 2,440-fold from bovine liver. The procedure developed was used to isolate the enzyme from 1,000 g of liver and permitted the rapid isolation of enzyme with a very high specific activity (40,405 mU/mg). The enzyme preparations obtained have been characterized by electrophoretic and spectrophotometric analysis and the molecular mass and the Stokes radius of the enzyme have been determined.
