Overexpression of aspartokinase gene in corynebacterium glutamicumfor higher production levels of l-lysine.
Thus, if aspartokinase is genetically altered to become resistant to the concerted feed back inhibition by threonine and L-lysine, then higher concentration of L-lysine would be produced, independent of concentration of threonine.
du Pont de Nemours and Company (Wilmington, DE) has patented four chimeric genes, a first encoding lysine-insensitive aspartokinase, which is operably linked to a plant chloroplast transit sequence, a second encoding lysine-insensitive dihydrodipicolinic acid synthase, which is operably linked to a plant chloroplast transit sequence, a third encoding a lysine-rich protein, and a fourth encoding a plant lysine ketoglutarate reductase, all operably linked to plant seed-specific regulatory sequences.
