Two methods are described for the assay of sulfotransferases which are active with sulfate acceptors bearing the hydroxyl functional group. Assays were developed for enzymes which transfer sulfate from 3′-phosphoadenosine–5′-phosphosulfate (PAP

Xanthine dehydrogenase (EC 1.2.1.37) is the first enzyme in the degradative pathway by which fungi convert purines to ammonia. In vivo, the activity is induced 6-fold by growth in uric acid. Hypoxanthine, xanthine, adenine, or guanine also induce enz

Five enzymes, active in the transfer of a methyl group to either oxygen, nitrogen or sulfur atoms, were inhibited competitively by a peptide isolated from rabbit liver. The peptide, named methinin, appears to have a chromophore that resembles pyridin
