The present disclosure relates to modified homoserine dehydrogenase and a method for producing a homoserine-derived L-amino acid using the same.

Nucleic acid encoding a modified homoserine dehydrogenase

Modified homoserine dehydrogenase and method for producing homoserine or L-amino acid derived from homoserine using the same

Provided is a method of producing-amino acids by using a recombinant coryneform microorganism in which the expression of a target gene is weakened by using a gene transcription inhibition method.

Method of producing L-amino acids

The present invention relates to a method for producing highly-concentrated L-amino acid and riboflavin simultaneously, and a microorganism for simultaneously producing L-amino acid and riboflavin. Specifically, the present invention relates to a modified microorganism for producing L-lysine or L-threonine, and riboflavin simultaneously, wherein the microorganism belonging tosp. capable of producing L-lysine or L-threonine is modified by enhancing the activity of an enzyme family expressed by a rib operon which contains riboflavin biosynthesis gene family. Also, the present invention relates to a method for the simultaneous production of L-lysine or L-threonine, and riboflavin using the modified microorganism, and relates to a formulation or granular formulation, feed, and feed additive, containing L-lysine or L-threonine, and riboflavin produced from a culture medium of the modified microorganism.

The present invention relates to a modified polynucleotide encoding aspartate kinase (EC:2.7.2.4; hereinafter, referred to as LysC), transketolase (EC:2.2.1.1; hereinafter, referred to as Tkt) or pyruvate carboxylase (EC:6.4.1.1; hereinafter, referred to as Pyc), in which the initiation codon is substituted with ATG, a vector including the same, a microorganism transformed with the vector, and a method for producing L-lysine using the same.

Method for producing L-lysine using microorganisms having ability to produce L-lysine

The present invention relates tosp. that is transformed with ansp.-derived fructokinase gene to express fructokinase showing a sufficient activity of converting fructose into fructose-6-phosphate, thereby preventing unnecessary energy consumption, and a method for producing L-amino acids using the strain. The transformedsp. of the present invention is able to express fructokinase from the-derived fructokinase gene to prevent unnecessary energy consumption during fructose metabolism, leading to more cost-effective production of L-amino acids. Therefore, it can be widely used for the effective production of L-amino acids.
