Fig. 1From: Metabolic engineering of Escherichia coli for de novo production of 3-phenylpropanol via retrobiosynthesis approachThe 3-phenylpropanol biosynthetic pathways. A The proposed pathway in S. cerevisiae [23, 24]. B The retrosynthetically designed artificial pathway in E. coli in this study. Green arrow indicated the heterologous enzymes: PAL l-phenylalanine ammonia lyase, CAR carboxylic acid reductase, PPTase phosphophantethinyl transferase, ER enoate reductaseBack to article page
