METHOD FOR THE FERMENTATIVE PRODUCTION OF L-LYSINE USING C. GLUTAMICUM STRAINS EXPRESSING MODIFIED GLUCONATE REPRESSOR PROTEINS GNTR1 AND GNTR2
C. glutamicum strains express modified gluconate repressor proteins GntR1 and GntR2. The C. glutamicum strains have an increased ability to produce L-lysine compared with an ability of a wildtype strain. The gluconate repressor protein GntR1 includes an amino acid sequence of SEQ ID NO: 9, where the...

| description | C. glutamicum strains express modified gluconate repressor proteins GntR1 and GntR2. The C. glutamicum strains have an increased ability to produce L-lysine compared with an ability of a wildtype strain. The gluconate repressor protein GntR1 includes an amino acid sequence of SEQ ID NO: 9, where the amino acid Arg in position 102 is replaced by the amino acid Glu. The gluconate repressor protein GntR2 includes SEQ ID NO: 10, and its activity is attenuated compared to the activity of the GntR2 repressor protein of the wild-type strain. A method is developed for the fermentative production of L-lysine using such C. glutamicum strains. |
