Background

Ferulic acid is best utilized as a precursor for synthesis of aromatic compounds such as vanillin, which involves 2 enzymes: the conversion of ferulic acid to feruloyl-CoA by feruloyl-CoA synthetase (Fcs) enzymes and the conversion of feruloyl-CoA into vanillin by enoyl-CoA hydratase/aldolase (Ech) enzymes BBa_K1129002 [1]. BBa_K1129001 is a feruloyl-CoA-synthetase (fcs) from Pseudomonas putida KT2440 which converts ferrulic acid to feruloyl CoA [2].

Experimental Data

Ech and fcs genes( BBa_K1129022 and BBa_K1129024), both of which are under constitutive promoters (BBa_J23118), were ligated into one pSB1C3 plasmid. An overnight culture of E.coli 10G cells harboring this plasmid was inoculated into a fresh culture of 5mL minimal media containing ferulic acid. Cells were then harvested for GC-MS after 7 hours of growth.

Similarly, ech and fcs genes (BBa_K1129021 and BBa_K1129023) under arabinose inducible promoters (BBa_I13453) were ligated together into one pSB1C3 plasmid. An overnight culture of E.coli 10G cells harboring this plasmid was inoculated into a fresh culture of 5mL minimal media containing ferulic acid and arabinose. Cells were then harvested for GC-MS after 7 hours of growth.
