    摘要: A genetically engineered Pseudomonas oleovorans phaC1 polyhydroxyalkanoate (PHA) polymerase having tailored substrate specificity is provided. The modified PHA polymerase is preferably a "bispecific" PHA polymerase capable of copolymerizing a short chain length monomer and a medium chain length monomer is provided. Methods for making the modified PHA polymerase and for making nucleic acids encoding the modified PHA polymerase are also disclosed, as are methods of producing PHA using the modified PHA polymerase. The invention further includes methods to assay for altered substrate specificity.
