Enhancement of  l-phenylalanine production in Escherichia coli by heterologous expression of Vitreoscilla hemoglobin.

Abstract

l-Phenylalanine is an important amino acid that is widely used in the production of food flavors and pharmaceuticals. Generally, l-phenylalanine production by engineered Escherichia coli requires a high rate of oxygen supply. However, the coexpression of Vitreoscilla hemoglobin gene (vgb), driven bya tac promoter, with the genes encoding 3-deoxy-d… (More)
