Abstract
This document describes biochemical pathways for producing 2,4-pentadienoyl-CoA by forming one or two terminal functional groups, comprised of carboxyl or hydroxyl group, in a C5 backbone substrate such as glutaryl-CoA, glutaryl-[acp] or glutarate methyl ester. 2,4-pentadienoyl-CoA can be enzymatically converted to 1,3-butadiene.
Claims56
A method of biosynthesizing glutarate methyl ester in a recombinant host, the method comprising enzymatically converting at least one of malonyl-[acp] and malonyl-CoA to glutarate methyl ester in said host using at least one polypeptide having malonyl-CoA O-methyltransferase activity and at least one polypeptide having thioesterase activity.
A method of making glutarate, said method comprising (i) enzymatically converting glutaryl-[acp] methyl ester to glutaryl-[acp] or glutaryl-CoA methyl ester to glutaryl-CoA using a polypeptide having pimeloyl-[acp] methyl ester methylesterase activity, and (ii) enzymatically converting glutaryl-[acp] or glutaryl-CoA to glutarate using at least one polypeptide having thioesterase activity, reversible CoA-ligase activity, a CoA-transferase activity, an acylating dehydrogenase activity, an aldehyde dehydrogenase activity, a glutarate semialdehyde dehydrogenase activity, or a succinate-semialdehyde dehydrogenase activity.

29-30. (canceled)
33-34. (canceled)
A recombinant host cell comprising at least one exogenous nucleic acid encoding a polypeptide having malonyl-CoA O-methyltransferase activity;
- and a polypeptide having thioesterase activity, the host producing glutarate methyl ester.
46-47. (canceled)
A recombinant host comprising at least one exogenous nucleic acid encoding a polypeptide having pimeloyl-[acp] methyl ester methylesterase activity, and at least one polypeptide having an activity selected from the group consisting of thioesterase activity, reversible CoA-ligase activity, a CoA-transferase activity, an acylating dehydrogenase activity, an aldehyde dehydrogenase activity, a glutarate semialdehyde dehydrogenase activity, and a succinate-semialdehyde dehydrogenase activity.
