H3631 Sigma

Hyaluronidase from bovine testes

Type VI-S, lyophilized powder, 3,000-15,000 units/mg solid

Synonym: Hyaluronate 4-glycanohydrolase, Hyaluronoglucosaminidase



Biochem/physiol Actions

Hyaluronidase degrades hyaluronan and has been found to be inappropriately regulated during cancer progression.

These enzymes randomly cleave β-N-acetylhexosamine-[1→4] glycosidic bonds in hyaluronic acid, chondroitin, and chondroitin sulfates.
