    摘要: The present invention relates to a nucleic acid sequence characterized in that it is derived from the wild nucleic acid sequence coding for a thymidine kinase, said nucleic acid sequence having at least one mutation in the region corresponding to the ATP binding site and conveniently a second mutation in the N-terminal region and/or C-terminal region. It also relates to variants of the wild thymidine kinase and their use in genic therapy.

    摘要: Enzyme combinations useful for destroying cells, particularly proliferative cells, are disclosed. In particular, a combination of the following enzymes has been found to enhance the toxicity of nucleoside analogues to proliferating cells: an enzyme that phosphorylates the non-toxic nucleoside analogue to generate a monophosphate analogue, an enzyme that phosphorylates the monophosphate analogue to generate a diphosphate analogue and an enzyme that phosphorylates the diphosphate analogue to generate a toxic triphosphate analogue. Vectors enabling the intracellular expression and transfer of the enzyme combinations, as well as their therapeutic use, particularly in anti-cancer gene therapy, are also disclosed.
