Transport engineering using tobacco transporter NtJAT1 enhances alkaloid production in Escherichia coli.

Transporters have been used in the production of plant metabolites in microorganisms. This study introduced a tobacco multidrug and toxic compound extrusion transporter, NtJAT1, into alkaloid-producing Escherichia coli cells. NtJAT1 expression enhanced alkaloid production secretion into the medium by 14 folds. Our findings further demonstrate the usefulness of the transport-engineering approach.
