Abstract
This application describes methods, including non-naturally occurring methods, for biosynthesizing 3-hydroxy-3-methylglutaryl-coA and intermediates thereof, as well as non-naturally occurring hosts for producing 3-hydroxy-3-methylglutaryl-coA. This application also describes methods, including non-naturally occurring methods, for biosynthesizing isoprene and intermediates thereof, as well as non-naturally occurring hosts for producing isoprene.
