A variant ofshows activity greater than the endogenous activity of aspartate aminotransferase, aspartate kinase, aspartate semialdehyde dehydrogenase, dihydrodipicolinate synthase, dihydropicolinate reductase and diaminopimelate dicarboxylase and additionally pyruvate carboxylase. The variant is used in a method of producing L-lysine.

Disclosed herein are ammonia-specific 5'-XMP aminase mutants and a method for preparing the same. A mutation is introduced into the active site of glutamine-dependent catalysis in 5&#x2032;-XMP aminase. The resulting 5&#x2032;-XMP aminase mutant is devoid of the glutamine-dependent activity and specifically reacts with external ammonia in converting 5&#x2032;-XMP into 5&#x2032;-GMP. Thus, the ammonia-specific 5&#x2032;-XMP aminase mutant is stabler within cells compared to the wild type, and can be useful in the industrial conversion of 5&#x2032;-XMP into 5&#x2032;-GMP.

The present invention relates to a method for producing lactic acid with high concentration and high yield usingCJLA0310 KCCM-10542 that is separated and identified from Kimchi. Lactic acid is a very important organic acid with a wide range of applications including food additive such as food preservative, condiment or acidifier, and industrial fields such as cosmetics, chemistry, metals, electronics, fabrics, dyeing textiles, and pharmaceutical industries. Particularly, lactic acid is an essential ingredient of polylactic acid, one of biodegradable plastics to replace recalcitrant non-biodegradable plastics which are main causes of environmental contamination.

The present invention provides a microorganism that belongs to the genusand has an inactivated inherent NCgl2053 dehydrogenase gene, and a method of producing L-lysine using the same. By using the microorganism, the yield of L-lysine is increased since an inherent NCgl2053 dehydrogenase gene is inactivated. According to the method, L-lysine can be produced with high yield.

The present invention provide a microorganism comprising an inactivated chromosomal tdcBC gene and an inactivated chromosomal pckA gene, which has remarkably improved productivity of L-threonine. Also, the present invention provides a method of producing L-threonine using the microorganism. The microorganism is prepared by incorporating by a recombination technique an antibiotic resistance gene into a pckA gene on the chromosome of a bacterial strain containing an L-threonine degradation-associated operon gene, tdcBC, which is inactivated. The microorganism has the effect of preventing degradation and intracellular influx of L-threonine due to the inactivation of the tdcBC operon gene, and includes more activated pathways for L-threonine biosynthesis. Therefore, the microorganism is useful for mass production of L-threonine because of being capable of producing L-threonine in high levels and high yields even in the presence of high concentrations of glucose.

A method for producing L-threonine using a microorganism is provided. In the method, the threonine dehydratase (tdc) gene existing in the genomic DNA of the microorganism is partially deactivated using a recombination technique. For a microorganism strain with enhanced activity of threonine operon-containing enzymes and the phosphoenolpyruvate carboxylase (ppc) gene, the tdc gene engaged in one of the four threonine metabolic pathways is specifically deactivated, thereby markedly increasing the yield of L-threonine.
