| 摘要 |
This invention relates to methods of modifying pyridoxal 5′phosphate (PLP) dependent enzymes to extend the serum half-life of the enzyme, extend the in vivo period of methionine depletion in a host, and decrease the immunogenicity of the enzyme. A preferred PLP-dependent enzyme to be modified is a methioninase, preferably a recombinant methioninase (rMETase). The invention further relates to compositions comprising a modified PLP-dependent enzyme and methods of using the same. |
