Figure 2From: Production of hydroxycinnamoyl anthranilates from glucose in Escherichia coliProduction of Avn D and Avn F in engineered E . coli coexpressing HCBT and Nt4CL1. Detection of Avn D (A) and Avn F (B) from the culture medium of the W3110 trpD9923 strain harboring the pAvn vector and fed with p-coumarate and caffeate (300 μM), respectively. ESI-MS spectra were obtained after LC-TOF MS analysis of the culture medium of engineered E. coli strains (upper panels) and of authentic standard solutions (lower panels).Back to article page
