Improvement in the Production of L-Lysine by Over-expression of Aspartokinase (ASK) in C.
The blockage of homoserine synthesis at homoserine dehydrogenase step results in the release of the concerted feed back inhibition by threonine and L- lysine on aspartokinase. The aspartic semialdehyde produced proceeds to L-lysine through the L-lysine biosynthetic pathway.
When feedback-insensitive aspartokinase and dihydrodipicolinic acid synthase, enzymes in the synthetic pathway of lysine, are expressed in soybean, a five-fold increase in the amino acid has been observed (Falco et al., 1995).
