    • The present invention relates to an L-arginine producing mutant strain, and a method for fabricating the same. In particular, the present invention relates to a polynucleotide comprising an argD2 gene (Ncgl2355) that is a putative gene of acetylornithine aminotransferase involved in arginine biosynthesis of Corynebacterium glutamicum, a polypeptide encoded by the polynucleotide, a recombinant vector comprising the polynucleotide, a transformant capable of producing L-arginine in a high yield, which is prepared by introducing the recombinant vector into an L-arginine producing host microorganism to overexpress the argD2 gene, and a method for producing L-arginine by culturing the transformant. The transformant of the present invention overexpresses the argD2 gene to produce L-arginine in a high yield, thereby being used in medicinal and pharmaceutical industries.
    • 本发明涉及L-精氨酸生产突变菌株及其制造方法。 特别地,本发明涉及包含argD2基因(Ncgl2355)的多核苷酸,其是参与谷氨酸棒杆菌的精氨酸生物合成的乙酰鸟氨酸氨基转移酶的推定基因,由该多核苷酸编码的多肽,包含多核苷酸的重组载体,能够转化的转化体 通过将重组载体导入产生L-精氨酸的宿主微生物以过表达argD2基因而制备L-精氨酸,以及通过培养转化体来生产L-精氨酸的方法。 本发明的转化体以高产率过表达argD2基因产生L-精氨酸,从而用于医药和制药工业。
