The present disclosure relates to a microorganism of the genushaving an increased L-amino acid producing ability, containing NADP-dependent glyceraldehyde-3-phosphate dehydrogenase derived from the genus. According to the present disclosure, the NADP-dependent glyceraldehyde-3-phosphate dehydrogenase derived fromsubsp.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

Method for producing L-amino acids using microorganism containing NADP-dependent glyceraldehyde-3-phosphate dehydrogenase

The present disclosure relates to an adenylosuccinate synthetase variant, a microorganism containing the same, and a method for preparing purine nucleotides using the microorganism.

Adenylosuccinate synthetase and method for producing purine nucleotides using the same

Provided are promoters and a method of producing L-amino acid using the same.

Promoter and use thereof

The present disclosure relates to a polynucleotide having a novel promoter activity, a composition for expressing a gene comprising the polynucleotide, a microorganism comprising the gene, and a method for preparing purine nucleotides using the microorganism.

Promoter and method for producing purine nucleotide using the same

Disclosed is a microorganism ofsp. producing O-acetyl homoserine, and a method of producing O-acetyl homoserine in high yield using the microorganism.

Microorganism producing O-acetyl homoserine and the method of producing O-acetyl homoserine using the same

The present disclosure relates to a protein having the activity of exporting O-acetylhomoserine and a novel modified protein thereof, a microorganism capable of producing O-acetylhomoserine with enhanced expression of the protein, and a method for producing O-acetylhomoserine using the microorganism.

Polypeptide having the activity of exporting O-acetyl-homoserine

The present disclosure relates to a microorganism producing O-acetylhomoserine with high efficiency and a method for producing O-acetylhomoserine and L-methionine using the microorganism. The present disclosure provides a microorganism producing O-acetylhomoserine having an enhanced activity of a protein which is predicted to export O-acetylhomoserine, and a method for producing O-acetylhomoserine and L-methionine using the microorganism.

Microorganism producing O-acetyl-homoserine and method for producing O-acetylhomoserine using the same

A method for the preparation of nicotinic acid, which includes the step of obtaining a culture solution containing quinolinic acid by incubating a microorganism having an ability to produce quinolinic acid, and the step of adding an acid to the culture solution and conducting a decarboxylation reaction.

Method for the preparation of nicotinic acid

The present invention relates to a novel protein having O-acetylhomoserine sulfhydrylase activity, a mutant protein thereof, a polynucleotide encoding the same, a recombinant vector comprising the polynucleotide, a microorganism transformed with the recombinant vector, and a method for producing methionine or acetic acid using the protein. The production method of the present invention has the advantage of producing L-methionine and acetic acid cost-effectively through having higher conversion rate and reduced reaction time compared to the existing methods, and it can minimize the amount of enzyme homogenate added when using the mutant protein, thereby easily producing L-methionine and acetic acid at high yield.

O-acetylhomoserine sulfhydrylase or mutant protein thereof, and method for converting to methionine using the same
