20100112671 | Host Cells for Production of Isoprenoid Compounds - 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. | 05-06-2010 |

20090004724 | METHOD FOR ENHANCING PRODUCTION OF ISOPRENOID COMPOUNDS - The present invention provides methods of producing an isoprenoid or an isoprenoid precursor in a genetically modified host cell. The methods generally involve modulating the level of hydroxymethylglutaryl-CoA (HMG-CoA) in the cell, such that the level of HMG-CoA is not toxic to the cell and/or does not substantially inhibit cell growth, but is maintained at a level that provides for high-level production of mevalonate, IPP, and other downstream products of an isoprenoid or isoprenoid pathway, e.g., polyprenyl diphosphates and isoprenoid compounds. The present invention further provides genetically modified host cells that are suitable for use in a subject method. The present invention further provides recombinant nucleic acid constructs for use in generating a subject genetically modified host cell, including recombinant nucleic acid constructs comprising nucleotide sequences encoding one or more mevalonate pathway enzymes, and recombinant vectors (e.g., recombinant expression vectors) comprising same. The present invention further provides methods for identifying nucleic acids that encode HMG-CoA reductase (HMGR) variants that provide for relief of HMG-CoA accumulation-induced toxicity. The present invention farther provides methods for identifying agents that reduce intracellular accumulation of HMG-CoA. | 01-01-2009 |
20100055754 | METHODS FOR INCREASING ISOPRENOID AND ISOPRENOID PRECURSOR PRODUCTION BY MODULATING FATTY ACID LEVELS - The present invention provides methods of increasing production of an isoprenoid or an isoprenoid precursor in a host cell, the methods generally involving modulating the level of activity of a fatty acid biosynthetic pathway enzyme in the host cell and/or culturing the host cell in a culture medium comprising a fatty acid or a compound that can be metabolized in a cell or broken down in the medium to yield a fatty acid and/or culturing the host cell in a culture medium having increased osmolarity. | 03-04-2010 |

20110209106 | METHOD FOR DESIGNING OPTICAL LITHOGRAPHY MASKS FOR DIRECTED SELF-ASSEMBLY - A method and a computer system for designing an optical photomask for forming a prepattern opening in a photoresist layer on a substrate wherein the photoresist layer and the prepattern opening are coated with a self-assembly material that undergoes directed self-assembly to form a directed self-assembly pattern. The methods includes: generating a mask design shape from a target design shape; generating a sub-resolution assist feature design shape based on the mask design shape; using a computer to generate a prepattern shape based on the sub-resolution assist feature design shape; and using a computer to evaluate if a directed self-assembly pattern of the self-assembly material based on the prepattern shape is within specified ranges of dimensional and positional targets of the target design shape on the substrate. | 08-25-2011 |
