Uroporphyrinogen decarboxylase (EC has been purified to homogeneity from bovine liver by using isoelectric and salt precipitations, followed by chromatography on DEAE-cellulose, phenyl-Sepharose, hydroxylapatite, and Sephacryl S-200. The purified enzyme is a monomer with an Mr approximately 57 000 and an isoelectric point at pH 4.6. Enzyme activity is optimal in buffers having an ionic strength of approximately 0.1 M and a pH of 6.8. The purified enzyme has a specific activity… CONTINUE READING
