Uricase is primarily used in medical and diagnostic applications. It is employed to treat conditions like gout and tumor lysis syndrome by breaking down uric acid into allantoin, which is more easily excreted by the kidneys. This enzyme is also utilized in clinical laboratories to measure uric acid levels in blood and urine, aiding in the diagnosis and monitoring of hyperuricemia. Additionally, uricase is used in biotechnology research to study purine metabolism and develop therapeutic agents targeting uric acid-related disorders. Its ability to efficiently degrade uric acid makes it valuable in both therapeutic and analytical settings.
