Characterization of recombinant Ftps. (A) UV–visible absorption spectra of recombinant Ftps (~16 μmol L⁻¹ Ftp_Ec, ~29 μmol L⁻¹ Ftp_Ab, ~20 μmol L⁻¹ Ftp_So, ~75 μmol L⁻¹ Ftp_Hd and ~18 μmol L⁻¹ Ftp_Tp), as isolated. The UV–visible absorption spectrum of Ftp_Tp is shown for comparison (black line). (B) FAD turnover by recombinant Ftps were measured as described previously (Deka et al. 2013a). Points are plotted as the mean of two samples after 20 min incubation at room temperature. The FAD turnover by the wild‐type TP0796 (Ftp_Tp) was published previously (Deka et al. 2013a). Data are presented as mean ± standard error (n = 2). Standard error of the data points were <0.13 μmol L⁻¹.
