Claims (9)

1. Бактерия - продуцент L-аминокислоты, принадлежащая к роду Escherichia, в которой продукция L-аминокислоты упомянутой бактерией увеличена за счет повышения активности белков, описанных в пунктах (А) или (В), в клетке упомянутой бактерии:1. A bacterium is an L-amino acid producer belonging to the genus Escherichia, in which the production of an L-amino acid by said bacterium is increased by increasing the activity of the proteins described in points (A) or (B) in the cell of said bacterium: (A) белок, который представлен аминокислотной последовательностью, приведенной в списке последовательностей под номером 2;(A) a protein that is represented by the amino acid sequence shown in sequence listing number 2; (B) белок, который представлен аминокислотной последовательностью, включающей делеции, замены, вставки или добавление одной или нескольких аминокислот в аминокислотную последовательность, приведенную в списке последовательностей под номером 2, и который обладает активностью, придающей бактерии повышенную устойчивость к L-фенилаланине, и/или аналогам аминокислот, таким как п-фторфенилаланин, 5-фтор-DL-триптофан;(B) a protein that is represented by an amino acid sequence including deletions, substitutions, insertions, or the addition of one or more amino acids to the amino acid sequence listed in sequence number 2, and which has an activity that confers bacteria an increased resistance to L-phenylalanine, and / or amino acid analogs such as p-fluorophenylalanine, 5-fluoro-DL-tryptophan; 2.

The bacterium according to claim 2, characterized in that the natural promoter in said DNA is replaced by a strong promoter. 5. Способ получения L-аминокислоты, включающий стадии: выращивания бактерии по любому из пп.1-4 в питательной среде, и; выделения из культуральной жидкости полученной и накопленной в ней L-аминокислоты.5. A method for producing an L-amino acid, comprising the steps of: growing a bacterium according to any one of claims 1 to 4 in a nutrient medium, and; the allocation from the culture fluid obtained and accumulated in it L-amino acids. 6. Способ по п.5, отличающийся тем, что L-аминокислотой является L-фенилаланин.6. The method according to claim 5, characterized in that the L-amino acid is L-phenylalanine. 7. Способ по п.6, отличающийся тем, что у указанной бактерии повышена экспрессия генов биосинтеза L-фенилаланина.7. The method according to claim 6, characterized in that said bacterium has increased expression of L-phenylalanine biosynthesis genes. 8. Способ по п.5, отличающийся тем, что L-аминокислотой является L-триптофан.8. The method according to claim 5, characterized in that the L-amino acid is L-tryptophan. 9. Способ по п.8, отличающийся тем, что у указанной бактерии повышена экспрессия генов биосинтеза L-триптофана.9. The method according to claim 8, characterized in that said bacterium has increased expression of L-tryptophan biosynthesis genes.
