    摘要: A method of synthesizing optically-active (S)-3-hydroxybutyric acid and (S)-3-hydroxybutyrate ester using a mutated microorganism is provided. More particularly, a mutated microorganism for preparing (S)-3-hydroxybutyric acid transformed with a gene encoding β-ketothiolase, a gene encoding (S)-3-hydroxybutyryl CoA dehydrogenase and a gene encoding acyl CoA hydrolase; a method of preparing (S)-3-hydroxybutyric acid using the mutated microorganism; a mutated microorganism for preparing (S)-3-hydroxybutyrate ester transformed with a gene encoding β-ketothiolase, a gene encoding (S)-3-hydroxybutyryl CoA dehydrogenase, a gene encoding acyl CoA hydrolase and a gene encoding lipase; and a method of preparing (S)-3-hydroxybutyrate ester using the mutated microorganism are provided.Accordingly, (S)-3-hydroxybutyric acid with high optical purity may be produced from acetyl CoA produced in glycolysis of a microorganism by a simple process involving the manipulation of a metabolic pathway by a recombinant gene introduced into the microorganism without using a high-cost metal catalyst or a substrate. Further, (S)-3-hydroxybutyrate ester and lactone of (S)-3-hydroxybutyrate ester may be simply produced from (S)-3-hydroxybutyric acid produced by the above method using lipase.

    摘要: The present invention relates to cells or plants that can produce polylactate or its copolymers and to a method for preparing polylactate or its copolymers using the same. More specifically, cells or plants with the ability to produce polylactate or hydroxyalkanoate-lactate copolymers comprise both a gene encoding an enzyme that converts lactate into lactyl-CoA and a gene encoding polyhydroxyalkanoate (PHA) synthase which uses lactyl-CoA as a substrate. Also described is a method for preparing polylactate or hydroxyalkanoate-lactate copolymers which comprises culturing the cells in a medium containing lactate or lactate and various hydroxyalkanoates or culturing the plants. Effective preparation of hydroxyalkanoate-lactate copolymer which comprises various hydroxyalkanoates as well as polylactate, using the cells or the plants, is disclosed.

    摘要: A novel Rhodococcus-E. coli shuttle vector comprising an origin of replication of a novel plasmid derived from Rhodococcus erythropolis IAM1484 and an origin of replication derived from E. coli, is disclosed. This shuttle vector replicates bidirectionally in E. coli and Rhodococcus. Also disclosed is a recombinant vector in which a target gene is operably linked to the shuttle vector, and microorganisms transformed with the recombinant vector. The shuttle vector is relatively small in size, can replicate in a variety of species of the genus Rhodococcus and has high replication stability in a host cell. Therefore, this shuttle vector is useful for cloning a variety of genes.
