Hyaluronidase is a polysaccharidase consisting of a single polypeptide chain of 450 amino acid residues and contains four disulfide bonds. Hyaluronidase is glycosylated and contains 5% mannose and 2.17% glucosamine (Borders & Raftery). Hyaluronidase cleaves endo-N-acetlyhexosaminic bonds in hyaluronic acid and chondroitin sulfate A and C to tetrasaccharide residues, as hyaluronic acid and chondroitin sulfate are often found in connective tissues. Hyaluronidase is frequently used with other proteases such as collagenase.
