Disclosed is a genetically modified microorganism into which a nucleic acid encoding an enzyme that catalyzes a reaction to reduce 3-oxoadipyl-CoA to 3-hydroxyadipyl-CoA is introduced. In the genetically modified microorganism, a nucleic acid encoding any one of the polypeptides described in (a) to (c) below is introduced or expression of the polypeptide is enhanced: (a) a polypeptide composed of an amino acid sequence represented by any one of SEQ ID NOs: 1 to 6 and 213, (b) a polypeptide composed of the same amino acid sequence as any one of the amino acid sequences, except that one or several amino acids are substituted, deleted, inserted, and/or added, and having enzymatic activity that catalyzes a reaction to reduce 3-oxoadipyl-CoA to 3-hydroxyadipyl-CoA, and (c) a polypeptide composed of an amino acid sequence with a sequence identity of not less than 70% to any one of the amino acid sequences and having activity to reduce 3-oxoadipyl-CoA to 3-hydroxyadipyl-CoA.
本发明公开了一种转基因微生物,在该微生物中引入了编码一种酶的核酸,该酶可催化将 3-氧代二酰-CoA 还原为 3-羟基二酰-CoA 的反应。在转基因微生物中,引入编码下述(a)至(c)中所述任何一种多肽的核酸或增强该多肽的表达:(a)由 SEQ ID NO:1至6和213中任何一个所代表的氨基酸序列组成的多肽,(b)由与上述氨基酸序列中任何一个相同的氨基酸序列组成的多肽,但其中一个或几个氨基酸被取代、删除、插入和/或添加,并具有催化将3-氧代二酰-CoA还原为3-羟基二酰-CoA的反应的酶活性,以及(c)由与上述氨基酸序列中任何一个相同的氨基酸序列组成的多肽,但其中一个或几个氨基酸被取代、删除、插入和/或添加、(c) 由氨基酸序列组成的多肽,该氨基酸序列与上述任何一个氨基酸序列的序列同一性不低于 70%,并具有将 3-氧代二磷酰-CoA 还原成 3-羟基二磷酰-CoA 的活性。
