Production of malate hydroxycinnamates in yeast. Representative LC–MS chromatograms obtained from analysis of the culture medium of a S. cerevisiae strain expressing 4CL5 and TpHCT2 are shown. The strain was fed with malate and p-coumarate or caffeate for the synthesis of p-coumaroyl malate (a) and phaselic acid (b), respectively
