Hyaluronidase that mediates hydrolysis of (1->3)-linkages between beta-D-glucuronate and N-acetyl-D-glucosamine residues in hyaluronate. Very specific to hyaluronate: not able to hydrolyze chitin, heparin or chondroitin sulfate. Random hydrolysis of (1->3)-linkages between beta-D-glucuronate and N-acetyl-D-glucosamine residues in hyaluronate. Hyaluronidase activity is inhibited by Mn(2+), Cu(2+) and Fe(3+). Optimum pH is 6.5. Optimum temperature is 45 degrees Celsius. Belongs to the glycosyl hydrolase 79 family.
