Xanthine oxidase (XOD) catalyses the oxidation of hypoxanthine into xanthine and xanthine into uric acid. The enzyme plays a key role in the purine metabolic pathway. Despite the presence of different XODs in prokaryotes, the functional and structural knowledge of prokaryotic XODs remain limited (compared with their well-known eukaryotic counterparts), thereby hindering their biochemical analysis and industrial application. Using genetic and biochemical analyses, we identified and characterised recombinant XOD (CcXOD(AB)) from Cellulosimicrobium cellulans ATCC21606. Bioinformatics analysis sug...
