                    | UPA00394 | urate degradation~Degradation of uric acid, a key compound in the degradation of purines. The ureide pathway, which mediates the oxidative degradation of uric acid to (S)-allantoin, represents the late stage of purine catabolism in most organisms. The metabolism of uric acid has a pivotal role in transforming the nitrogen that is fixed in leguminous plants and also plays a crucial role in some bacteria under nitrogen-limited conditions. | Both - {{t,f}} | None - {{∅}} | Ambiguous |  |
