Abstract
A yeast cell, preferably Saccharomyces cerevisiae, which contains a functional stable recombinant DNA sequence that does not allow for the encoding of a negative regulator of phospholipid biosynthesis therein and which has multiple copies of an INO1 gene. In a preferred embodiment, the recombinant DNA sequence is an OPI1 gene deletion which results in the deregulation of inositol or inositol-containing metabolites such as inositol-1-phosphate synthase. Moreover, there is a method for obtaining inositol, inositol-containing metabolites or phospholipids such as myo-inositol or inositol-1-phosphate. The method comprises the steps of genetically engineering a stable yeast cell, preferably Saccharomyces cerevisiae, to continually produce inositol, inositol-containing metabolites or phospholipids. Additionally, there is the step of then generating the inositol, inositol-containing metabolites or phospholipids. In a preferred embodiment, the genetically engineering step includes the step of altering the negative regulatory step involved in phospholipid biosynthesis to overproduce inositol, inositol-containing metabolites or phospholipids such as myo-inositol.
