ABSTRACT:
Disclosed are a fusion protein comprising enzyme N-acetylgalactosamine-6-sulfate sulfatase and a short peptide consisting of 4-15 acidic amino acids attached to the enzyme on its N-terminal side, a pharmaceutical composition containing the fusion protein, and a method for treatment of type A Morquio disease using the fusion protein. Compared with the native enzyme protein, the fusion protein exhibits higher transferability to bone tissues and improved, higher stability in the blood.
