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.
Claims7
An L-threonine or L-tryptophan producing recombinant Escherichia coli strain, wherein the strain is modified by deletion of at least one polynucleotide, wherein the polynucleotide is selected from the group consisting of SEQ ID NO:
- 1, SEQ ID NO:
- 3, and SEQ ID NO:
- 5.
A method for producing L-threonine or L-tryptophan, the method comprising culturing an L-threonine or L-tryptophan producing recombinant Escherichia coli strain, wherein the strain is modified by deletion of at least one polynucleotide, wherein the polynucleotide is selected from the group consisting of SEQ ID NO:
- 1, SEQ ID NO:
- 3, and SEQ ID NO:
- 5.
