  Provided is a method of preparing polylactate (PLA) or a copolymer thereof using a mutant microorganism in which a gene participating in a coenzyme A (CoA) donor- and lactate-producing pathway is genetically manipulated to increase the productivity of a CoA donor and lactate. Amounts of the CoA donor and the lactate are simultaneously increased in a microbial metabolic pathway to enable effective biosynthesis of PLA and a hydroxyalkanoate-lactate copolymer having a high content of lactate, which is industrially useful.

  本发明提供了一种利用突变微生物制备聚乳酸（PLA）或其共聚物的方法，在这种突变微生物中，参与辅酶A（CoA）供体和乳酸盐产生途径的基因受到遗传操作，以提高CoA供体和乳酸盐的产量。在微生物代谢途径中，CoA 供体和乳酸盐的数量同时增加，从而能够有效地生物合成聚乳酸和具有高乳酸盐含量的羟基烷酸-乳酸盐共聚物，这在工业上是有用的。

  Mutants of various polyhydroxyalkanoate (PHA) synthases capable of synthesizing a lactate polymer (PLA) and a lactate copolymer (PLA copolymer), and a method of preparing a lactate polymer and a lactate copolymer using the same are provided. More specifically, a mutant of polyhydroxyalkanoate synthase set forth in SEQ ID NO: 2, 4, 6, or 8, and a method of preparing lactate polymer and lactate copolymer using the mutant of synthase are provided. The polyhydroxyalkanoate synthase set forth in SEQ ID NO: 2, 4, 6, or 8 can have an activity of synthesizing a lactate polymer and a lactate copolymer by an amino acid sequence mutation affecting an activity of synthesizing a lactate polymer, and can produce a lactate polymer and a copolymer that have different features, respectively, by using the mutants of the synthase.

  Provided is a mutant of propionyl-CoA transferase from Clostridium propionicum that can convert lactate into lactyl-CoA with high efficiency in a method of preparing a polylactate (PLA) or PLA copolymer using microorganisms. Unlike conventional propionyl-CoA transferase which is weakly expressed in E.coli, when a mutant of propiony-CoA transferase from Clostridium propionicum is introduced into recombinant E.coli, lactyl-CoA can be supplied very smoothly, thereby enabling highly efficient preparation of polylactate (PLA) and PLA copolymer.

  本文提供了一种来自丙酸梭菌的丙酰-CoA 转移酶突变体，在利用微生物制备聚乳酸（PLA）或聚乳酸共聚物的方法中，该突变体可高效地将乳酸转化为乳酰-CoA。与传统的丙酰基-CoA 转移酶在大肠杆菌中弱表达不同，当将丙酸梭状芽孢杆菌的丙酰基-CoA 转移酶突变体引入重组大肠杆菌时，乳酰-CoA 的供应非常顺畅，从而能够高效制备聚乳酸（PLA）和聚乳酸共聚物。
