Apple fragrance generator

The apple fragrance generator (BBa_K395602) catalyzes the conversion of 2-methylbutanol and butanol to 2-methybutyl acetate and butyl acetate that has a apple fragrance. The biosynthetic device is composed of two devices:fragrance enzyme generator (BBa_K395601) and a T7 terminator (BBa_K395600).


We designed apple fragrance expression device with MpAAT1[1]. Fig. 1 shows the outline of the device. MpAAT1 converts substrate and Acetyl CoA into apple fragrance molecules.　Acetyl CoA exists originally in E.coli cell. MpAAT1 converts 2-methyl butanol and butanol into 2-methylbutyl acetate and butyl acetate respectively.

We performed gas chromatography to confirm the production of the esters, and the results revealed that MpAAT1 successfully converted alcohol and Acetyl CoA into our target esters (Fig. 2).
