  • Microorganism able to Produce L-Amino Acid, and Method for Producing L-Amino Acid by Using the Same
    Publication number: 20150050703
    Abstract: The present invention relates to a microorganism able to produce L-threonine or L-tryptophan, and to a method for producing L-threonine or L-tryptophan by using same. More specifically, the present invention relates to: recombinant Escherichia coli which is more efficient in producing L-threonine or L-tryptophan by increasing the ability to produce ATP which is used as the most plentiful energy source in cells when producing L-threonine or L-tryptophan; and a method for producing L-threonine or L-tryptophan by using same.

  • Method of producing L-threonine using strain with phosphoenolpyruvate carboxylase promoter replaced with cysteine synthase promoter
    Patent number: 8486670
    Abstract: An L-threonine-producing Escherichia coli in which a promoter of a phosphoenolpyruvate carboxylase (ppc) gene on the chromosome is substituted with a promoter of a cysteine synthase (cysK) gene and a method of producing L-threonine by using the same are disclosed. The recombinant Escherichia coli may produce L-threonine in a high yield, and thus may be widely used in medical, pharmaceutical, and feed industries, particularly for an animal feed.
