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.

摘要: A method to assess the level of folate in a biological sample comprises: providing said sample with glycine N-methyltransferase (GMT) and with an excess of S-adenosyl methionine (SAM) and of glycine; providing a control which contains no folate with said GMT and excess SAM and glycine in comparable amounts to those provided to the sample; and comparing the concentration of at least one product formed in the sample with the concentrations of said product formed in the control, whereby the difference in levels of said product in the sample as compared to the control is directly proportional to the level of folate in the sample.
