Title: (EN) Host cells and methods for producing isopentenol from mevalonate
Abstract: front page image
(EN)

The present invention provides for a genetically modified host cell capable of producing isopentenol and/or 3-methyl-3-butenol, comprising (a) an increased expression of phosphomevalonate decarboxylase (PMD) (b) an increased expression of a phosphatase capable of converting isopentenol into 3-methyl-3-butenol, (c) optionally the genetically modified host cell does not express, or has a decreased expression of one or more of NudB, phosphomevalonate kinase (PMK), and/or PMD, and (d) optionally one or more further enzymes capable of converting isopentenol and/or 3-methyl-3-butenol into a third compound, such as isoprene.
