Hyaluronidase catalyzes the hydrolysis of hyaluronic acid (HA), an anionic, nonsulfated glycosaminoglycan distributed widely throughout connective, epithelial, and neural tissues (PubMed:28479398). In venom, they are known to enhance diffusion of the venom by degrading the extracellular matrix (Probable). Random hydrolysis of (1->4)-linkages between N-acetyl-beta-D-glucosamine and D-glucuronate residues in hyaluronate. Expressed by the venom duct. Glycosylated. Belongs to the glycosyl hydrolase 56 family.
