  • Patent number: 7422884
    Abstract: The present invention relates to modified mevalonate kinases that are less sensitive to feedback inhibition, and to polynucleotides encoding them. The invention further pertains to vectors comprising these polynucleotides and host cells containing such vectors. The invention provides a method for producing the modified enzyme and a method for producing isoprenoid compounds.

  • Patent number: 7232679
    Abstract: Isolated polynucleotides encoding polypeptides having the activity of enzymes in the mevalonate pathway are provided. These sequences are useful for recombinantly producing isoprenoid compounds, such as carotenoids, in particular zeaxanthin. Expression vectors, cultured cells, and methods of making isoprenoid compounds are also provided.

  • Patent number: 6204012
    Abstract: A method for producing a protein by culturing a cell capable of expressing the protein and which contains a methylotrophic yeast promoter for an enzyme of the methanol metabolic pathway controlling expression of the protein, in a fermentative batch process comprising a batch phase and a feeding phase, under conditions such that dissolved oxygen is continually present in the culture medium throughout the process, and about 1% to about 100% of the carbon source during the feeding phase is a sugar or sugar polymer, which sugar or sugar polymer is provided in such an amount that the sugar or sugar polymer is continually depleted by the cell and therefore is substantially undetectable in the culture medium; and isolating the protein on completion of the feeding phase.
