摘要:
The present invention provides Phenylalanine Hydroxylase (PAH) fusion proteins and pharmaceutical compositions comprising the same, as well as encoding polynucleotides and vectors, and methods for treating hyperphenylalaninemia, including PKU, by enzyme replacement therapy. The fusion proteins have phenylalanine hydroxylase activity when administered: and have an increased half-life or persistence in circulation, as compared to unfused counterparts. The PAH fusion proteins are suitable for enzyme replacement therapy in PKU patients by converting phenylalanine in the circulation to tyrosine, thereby controlling phenylalanine levels.
