Abstract
Recombinant hosts for producing polyhydroxyalkanoates and methods of producing polyhydroxyalkanoates from renewable carbon substrates are provided. Certain recombinant hosts that produce 5 carbon chemicals such as 5-aminopentanoate (5AP), 5-hydroxyvalerate (5HV), glutarate, and 1,5 pentanediol (PDO) are also provided. One embodiment provides a recombinant host expressing a gene encoding a heterologous enzyme selected from the group consisting of a polyhydroxyalkanoate synthase and a 5-hydroxyvalerate-CoA (5HV-CoA) transferase, wherein the host produces a polymer containing 5-hydroxyvalerate. Preferably, the host expresses both a polyhydroxyalkanoate synthase and a 5HV-CoA transferase. The host can be prokaryotic or eukaryotic. A preferred prokaryotic host is E. coli. The polymers produced by the recombinant hosts can be homopolymers or copolymers of 5-hydroxyvalerate. A preferred copolymer is poly(3-hydroxybutyrate-co-5-hydroxyvalerate).
