Fig. 4From: Construction of a new T7 promoter compatible Escherichia coli Nissle 1917 strain for recombinant production of heme-dependent proteinsRed-Farred induced difference spectra of the phytochrome BphP from P. aeruginosa. BphP was co-produced with the heme oxygenase HO1 (T7 promoter) for biliverdin production in E. coli BL21(DE3), EcN and EcN(T7). The calculated difference spectra were smoothed using a 25 points Savitzky-Golay filterBack to article page
