  • Publication number: 20070166782
    Abstract: Methods for synthesizing isopentenyl pyrophosphate are provided. A first method comprises introducing into a host microorganism a plurality of heterologous nucleic acid sequences, each coding for a different enzyme in the mevalonate pathway for producing isopentenyl pyrophosphate. A related method comprises introducing into a host microorganism an intermediate in the mevalonate pathway and at least one heterologous nucleic acid sequence, each sequence coding for an enzyme in the mevalonate pathway necessary for converting the intermediate into isopentenyl pyrophosphate. The invention also provides nucleic acid sequences, enzymes, expression vectors, and transformed host cells for carrying out the methods.

  • Publication number: 20070141574
    Abstract: The present invention provides isolated, genetically modified host cells, where a host cell is genetically modified with a nucleic acid that includes a nucleotide sequence encoding a biosynthetic pathway enzyme. Synthesis of the enzyme in the host cell results in conversion of a substrate for the enzyme into a biosynthetic pathway intermediate, which intermediate is produced in an amount effective to inhibit growth of the genetically modified host cell. The present invention further provides compositions and kits comprising a subject genetically modified host cell. Subject host cells are useful for identifying a gene product having activity in a biosynthetic pathway. The present invention further provides methods of identifying a gene product having activity in a biosynthetic pathway.
