Extended Data Fig. 1: TnaA activities toward Trp and 6-Br-Trp in the whole-cell reaction.
From: Production of Tyrian purple indigoid dye from tryptophan in Escherichia coli
a, Trp and 6-Br-Trp consumption was monitored in the whole-cell reaction of the strain ΔtnaA TnaA for 6 h. Data are presented as mean values ± s.d. from three biologically independent samples. b, HPLC chromatograms of the reactions with Trp (B, C and D) or 6-Br-Trp (E, F and G), respectively, at different time points. A: Authentic standards: Trp; phenol as an internal standard; and 6-Br-Trp. B, C and D: The reaction using Trp at 0 h, 1 h and 6 h. E, F and G: The reaction using 6-Br-Trp at 0 h, 1 h and 6 h.
