Abstract
The invention provides a biological method of producing isoprenoids.
Claims16
A recombinant yeast having an endogenous mevalonate pathway comprising:
- an enzyme that converts acetyl-CoA to acetoacetyl-CoA (thiolase), an enzyme that converts acetoacetyl-CoA to hydroxymethylglutaryl-CoA (HMG Co A synthase;
- HMGS), an enzyme that converts hydroxymethylglutaryl-CoA to mevalonic acid (HMG Co A reductase;
- HMGR), an enzyme that converts mevalonic acid to phosphomevalonic acid (mevalonate kinase;
- MK), an enzyme that converts phosphomevalonic acid to phosphomevalonate (phsophomevalonate kinase;
- PMK), and an enzyme that converts phosphomevalonate to isopentenyl pyrophosphate (phsophomevalonate decarboxylase;
- PMD) that is capable of making an isoprenoid compound comprising:
- a heterologous HMGR;
- a heterologous MK;
- a heterologous PMK;
- a heterologous PMD;
- and
- at least one heterologous nucleic acid molecule that encodes an enzyme that increases the supply of acetyl-CoA to an isoprenoid biosynthetic pathway selected from the group consisting of an enzyme that converts phosphoenolpyruvate to pyruvate and, an enzyme that converts pyruvate to acetyl-CoA,
- wherein the yeast has more copies of HMGR encoded by the nucleic acid molecules than thiolase and HMGS and the yeast has more copies of MK, PMK, and PMD encoded by the nucleic acid molecules than thiolase and HMGS.
