摘要:
The present invention relates to a copolymer comprising 3-hydroxyalkanoate monomer unit and lactate monomer unit, or their preparing method. More specifically, the present invention relates to a method for preparing a copolymer comprising lactate monomer and 3-hydroxyalkanoate monomer, wherein the method comprises culturing a cell or plant comprising the gene of enzyme converting lactate and 3-hydroxyalkanoate into lactyl-CoA and 3-hydroxyalkanoyl-CoA, respectively, and polyhydroxyalkanoate synthase gene together, and the copolymer made by the method. The copolymer of the present invention is a biodegradable polymer being able to be usefully used instead of conventional synthetic plastic, and the copolymer can be used also for medical use.
摘要:
The present invention relates to polyhydroxyalkanoate synthase (PHA synthase) mutant originated from Pseudomonas sp. 6-19 (KCTC 11027BP) which can prepare lactate polymer and/or copolymer by using lactyl-CoA as a substrate. The present invention relates to a method for preparing lactate polymer and/or copolymer with the synthase mutant. The polyhydroxyalkanoate synthase mutants of the present invention originated from Pseudomonas sp. 6-19 can efficiently prepare lactate polymer and/or copolymer by using as a substrate lactyl-CoA which is difficult to be used as a substrate by conventional polyhydroxyalkanoate synthase.

摘要:
A mutant capable of producing 1,4-butanediol and a method of preparing 1,4-butanediol using the same are provided. The mutant microorganism is prepared by introducing and amplifying genes encoding enzymes converting succinate into 4-hydroxybutyrate and 4-hydroxybutyrate into 1,4-butanediol in a microorganism capable of producing succinate. The method includes culturing the mutant in a medium containing carbohydrate and obtaining 1,4-butanediol from the culture. Thus, 1,4-butanediol, which is essential in chemical industry, can be prepared in a biological process.
