Part:BBa_K1060003

Methyl Salicylate Production

KU_Leuven 2013 requested the BBa_J45700 brick from MIT 2006 and recloned into the pSB1C3 standard plasmid backbone. For the assembly of this part we refer to the original MIT brick BBa_J45700 => "We assembled a complete wintergreen odor biosynthetic system (BBa_J45700) by combining the salicylic acid (BBa_J45320) and wintergreen odor generators (BBa_J45120). BBa_J45700 catalyzes the conversion of the cellular metabolite chorismate to methyl salicylate or wintergreen odor."

Headspace Gas-Chromatography

Samples were analyzed with a calibrated Autosystem XL gas chromatograph with a headspace sampler (HS40; Perkin-Elmer, Wellesley, Mass.) and equipped with a CP-Wax 52 CB column. Headspace GC was performed on pure MeS (Sigma-Aldrich) (A), on culture supernatant from a E. coli BL21 strain harbouring BBa_K1060003 without (B) or with 0.1 mM salicylic acid (C). MeS could be detected at 12.832 minutes in (A) and (C) but not when no salicylic acid was added.
