Improvement of Reticuline Productivity from Dopamine by Using Engineered Escherichia coli

抄録

Benzylisoquinoline alkaloids (BIAs) are pharmaceutically important compounds. We have previously devised a reticuline (BIA) production method from dopamine by using Escherichia coli; however, its productivity was relatively low (33 µM, 11 mg/L). We report here, by fine-tuning the method, higher reticuline productivity of 165 µM (54 mg/L), increasing the conversion efficiency by 8-fold. These results are important for developing an efficient route to fermentative reticuline production.
