Synergetic engineering of for efficient production of l-tyrosine.

l-Tyrosine, an aromatic non-essential amino acid, is the raw material for many important chemical products, including levodopa, resveratrol, and hydroxytyrosol. It is widely used in the food, drug, and chemical industries. There are many studies on the synthesis of l-tyrosine by microorganisms, however, the low titer of l-tyrosine limited the industrial large-scale production.
