construction of a valine producer by genetic engineering, mutant strains are resistant against inhibition by branched-chain amino acids L-valine, L-isoleucine and L-leucine, A constructed weak promoter of ilvA or leuA, which is introduced into the Corynebacterium glutamicum chromosome via a gene-replacement technique, reduces the biosynthetic rate of isoleucine or leucine, which lowers the mutant growth rate and increases valine production. Overexpression of ilvD driven by the strong mutant promoter P-ilvDM7 resultsin an even higher level of valine production, engineered strains, overview |

engineering of wild-type Corynebacterium glutamicum for growth-decoupled production of 2-ketoisovalerate from glucose by deletion of the aceE gene encoding the E1p subunit of the pyruvate dehydrogenase complex, deletion of the transaminase B gene ilvE, and additional overexpression of the ilvBNCD genes, encoding the L-valine biosynthetic enzymes acetohydroxyacid synthase, acetohydroxyacid isomeroreductase, and dihydroxyacid dehydratase. 2-Ketoisovalerate production is further improved by deletion of the pyruvate:quinone oxidoreductase gene pqo. In fed-batch fermentations at high cell densities, the constructed strains produce up to 188 mM 2-ketoisovalerate and show a product yield of about 0.47 mol per mol of glucose and a volumetric productivity of about 4.6 mM 2-ketoisovalerate per h in the overall production phase, overview |
