Fig. 5. Employing pathway modularity to diversify phenylpropene biosynthesis.
Overview of modular arrangements to synthesize distinct phenylpropene products via downstream enzyme promiscuity for diverse hydroxycinnamic acid pathway intermediates. A Use of complete forms of Modules I-III to produce eugenol. B Removal of COMT from Module II to direct flux to hydroxychavicol production. C Removal of Module II entirely to enable chavicol accumulation.
