Exponential phase wintergreen odor biosynthetic system

We assembled a complete, exponential phase dependent wintergreen odor biosynthetic system (BBa_J45800) by combining the salicylic acid (BBa_J45320) and exponential phase dependent wintergreen odor generators (BBa_J45180). BBa_J45800 catalyzes the conversion of the cellular metabolite chorismate to methyl salicylate or wintergreen odor. Wintergreen odor should only be produced in exponentially growing cells.

Usage and Biology

To construct a complete wintergreen odor biosynthetic system, we needed to design an additional biosynthetic device for wintergreen odor precursor production. We designed a biosynthetic device for production of salicylate from the cellular metabolite chorismate (BBa_J45320) based on the pchBA genes from Pseudomonas aeruginosa. The enzyme PchA, an isochorismate synthase, catalyzes the conversion of chorismate to isochorismate. The enzyme PchB, an isochorismate pyruvate-lyase, catalyzes the conversion of isochorismate to salicylate and pyruvate. Serino et al. previously demonstrated salicylate formation in E. coli using the pchBA genes.
