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.
