β-Glucuronidase, a member of the 2 glycosyl hydrolase family, is involved in the hydrolysis of β-glucuronic acid residues from the non-reducing termini of glycosaminoglycans (GAGs). β-Glucuronidase catalyzes the complete hydrolysis of urinary conjugates. β-Glucuronidase serves as a possible candidate enzyme for gene-mediated enzyme prodrug therapy for glucuronide prodrugs. β-glucuronidase-responsive albumin binding prodrugs might be an effective therapeutic practice for treating solid tumors.
