Fig. 8From: Exploiting members of the BAHD acyltransferase family to synthesize multiple hydroxycinnamate and benzoate conjugates in yeastProduction of tropane alkaloids in yeast. Representative LC–MS chromatograms obtained from analysis of the culture medium of a S. cerevisiae strain expressing 4CL5 and EcCS are shown. The strain was fed with 3β-tropine and cinnamate or benzoate for the synthesis of cinnamoyl 3β-tropine (a) and tropacocaine (c), respectively. Note the double LC–MS peaks suggesting the presence of two isomers for each product. The LC–MS chromatogram of a solution of authentic cinnamoyl 3β-tropine is also shown (b)Back to article page
