synthesis | the enzyme is a potential target for improved production of L-lysine. Recombinants of Corynebacterium glutamicum with feedback resistant aspartate kinase would be a potential option to increase the L-lysine production by biotechnological process for industrial application | Corynebacterium glutamicum |

additional information | site-directed mutagenesis is used to construct a mutant of the region coding for regulatory beta-subunit in the aspartate kinase by replacing the codon TCC-GTC to deregulate it from feedback inhibition, which results in improved L-lysine production. The mutant enzymes are resistant against S-(2-aminoethyl)-L-cysteine and feedback inhibition, phenotype, overview | Corynebacterium glutamicum |
