Production of isoprenoids
View Patent ↗The invention provides a biological method of producing isoprenoids.
1. 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.
2. The yeast of claim 1 wherein the at least one heterologous nucleic acid molecule is on a plasmid.
3. The yeast of claim 1 wherein the at least one heterologous nucleic acid molecule is chromosomally integrated.
4. The yeast of claim 1 wherein the at least one heterologous nucleic acid molecule is under inducible control.
5. The yeast of claim 1 wherein the yeast is Saccharomyces cerevisiae.
6. The yeast of claim 1 wherein the heterologous nucleic acid molecule encodes an enzyme that converts phosphoenolpyruvate to pyruvate.
7. The yeast of claim 6 wherein the heterologous nucleic acid molecule is on a plasmid.
8. The yeast of claim 6 wherein the heterologous nucleic acid molecule is chromosomally integrated.
9. The yeast of claim 6 wherein the heterologous nucleic acid is under inducible control.
10. The yeast of claim 1 wherein the heterologous nucleic acid molecule encodes an enzyme that converts pyruvate to acetyl-CoA.
11. The yeast of claim 10 wherein the heterologous nucleic acid molecule is on a plasmid.
12. The yeast of claim 10 wherein the heterologous nucleic acid molecule is chromosomally integrated.
13. The yeast of claim 10 wherein the heterologous nucleic acid is under inducible control.
14. The yeast of claim 1 wherein the heterologous nucleic acid molecule that encodes an enzyme that converts hydroxymethylglutaryl-CoA to mevalonic acid is a eukaryotic nucleic acid.
15. The yeast of claim 1 wherein the heterologous nucleic acid molecule that encodes an enzyme that converts hydroxymethylglutaryl-CoA to mevalonic acid is a bacterial nucleic acid.
16. The yeast of claim 1 , wherein the heterologous nucleic acid molecule that encodes an enzyme that converts hydroxymethylglutaryl-CoA to mevalonic acid is a yeast nucleic acid.
