Increased isoprene production using the archaeal lower mevalonate pathway

摘要

The invention features methods for producing isoprene from cultured cells using a feedback-resistant mevalonate kinase polypeptide, such as an archaeal mevalonate kinase polypeptide. The resulting isoprene compositions may have increased yields and/or purity of isoprene.

主权项

1. A method of producing isoprene, the method comprising
(a) culturing recombinant cells comprising (i) one or more heterologous nucleic acids encoding feedback-resistant mevalonate kinase polypeptides, (ii) one or more heterologous nucleic acids encoding an isoprene synthase polypeptide or one or more additional copies of an endogenous nucleic acid encoding an isoprene synthase polypeptide, and (iii) one or more nucleic acids encoding a mevalonate (MVA) pathway polypeptide under suitable culture conditions for the production of isoprene, and (b) producing isoprene.
