  • Publication number: 20220348973
    Abstract: The present disclosure relates to a microorganism of the genus Corynebacterium having an increased L-amino acid producing ability, containing NADP-dependent glyceraldehyde-3-phosphate dehydrogenase derived from the genus Lactobacillus. According to the present disclosure, the NADP-dependent glyceraldehyde-3-phosphate dehydrogenase derived from Lactobacillus delbrueckii subsp. bulgaricus is introduced to increase the reducing power through the activity of NADP-dependent glyceraldehyde-3-phosphate dehydrogenase, thereby increasing the L-amino acid producing ability of the strains belonging to the genus Corynebacterium.

  • Patent number: 10113191
    Abstract: Disclosed are a recombinant microorganism having enhanced L-amino acid productivity, wherein the recombinant microorganism is transformed to have removed or decreased activity of at least one of adenosine deaminase and AMP nucleosidase, and a method of producing an L-amino acid using the recombinant microorganism. The use of the recombinant microorganism may enable the production of the L-amino acid in a highly efficient manner.
