Fig. 2From: Metabolic engineering of Escherichia coli BL21 (DE3) for de novo production of l-DOPA from d-glucosel-DOPA production from hpaB randomly generated mutants. HpaB variants showed an increased l-DOPA production compared to the wild-type hpaB. White bars: l-DOPA; Black bars: l-tyrosine. A: E. coli LP-7; B. E. coli LP-8; C. E. coli LP-9; B. E. coli LP-10Back to article page
