👉 Glucuronidase is a type of enzyme that catalyzes the hydroxylation of glucuronic acid, a sugar found in proteins and other macromolecules. Glucuronidases convert the sugar into a keto acid (glutamate) and a nitrogenous group (glutamine), which are then incorporated into the protein structure. This process is essential for the proper functioning of many biological processes including cell division, immune response, and hormone synthesis.
