Extended Data Fig. 8: Synthesis scheme of dihalogenated indigos through the fusion strategy and the consecutive two-cell reaction system.
From: Production of Tyrian purple indigoid dye from tryptophan in Escherichia coli
Fre-L3-PyrH, Fre-L3-SttH, and Fre-L3-RebH were used to produce halogenated tryptophans. TnaA and MaFMO were used to produce dihalogenated indigos from the halogenated tryptophans.
