Fig. 5: Representative results for GC-MS analysis of compounds generated by five TPS genes in E. coli.

a Profile for a control group and the transformed E. coli cells cultivated in buffer without IPTG and GPP; b A representative profile following the transformation of the LrlTPS-3 gene and the addition of IPTG and GPP. Since the five recombinant protein showed the same activity in converting GPP into three monoterpenes, only one representative profile is presented
