The present disclosure relates to a modified polypeptide, in which the activity of meso-diaminopimelate is weakened, and a method for producing L-threonine using the same.

The present disclosure relates to a novel polypeptide having an ability to export an ornithine-based product, and a method for producing an ornithine-based product using the same.

Provided are a novel L-threonine dehydratase variant and a method of producing L-isoleucine using the same.

Provided are a novel L-threonine dehydratase variant and a method of producing L-isoleucine using the same.

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.
