Abstract: The present invention relates to a mutant organism having the ability to produce aspartic acid derivatives, wherein a gene encoding the glyoxylate shunt regulator and a gene encoding fumarase are deleted and a gene encoding aspartase is overexpressed compared to that in a wild-type strain, and to a method for producing L-aspartic acid derivatives using the same. According to the present invention, various aspartic acid derivatives, including L-alanine, 3-aminopropionic acid, threonine, 1,3-diaminopropane, lysine, methionine, 3-hydroxypropionic acid, cadaverine, 5-aminovaleric acid, etc., can be produced by biological methods.

Abstract: The present disclosure relates to a recombinant microorganism having a lactam production capacity from an omega-amino acid, into which a gene encoding a beta-alanine coenzyme A transferase on a microorganism which has an omega-amino acid biosynthetic metabolic pathway inherently or an omega-amino acid biosynthetic metabolic pathway is introduced, and a method for producing a variety of lactams and omega-amino acyl-CoAs using the same.The recombinant microorganism and the method for producing the lactam according to the present disclosure are useful in producing a variety of lactams such as propiolactam, 2-pyrrolidone, valerolactam, caprolactam, and heptanolactam from a variety of omega-amino acids.
