Introduction

The promoter TEF1 is a constitutive promoter that comes from the plasmid p405TEF1 from Nicolas Buchler & Fred Cross (unpublished). The TEF1 promoter coming from the yeast Y. lipolitica is already described and used in part (BBa_K2117000), but ours comes from the S. cerevisiae genome.

Results

Production of β-ionone (BBa_K3930003)

The part (BBa_K3930002) was linearized and transformed into the S.cerevisiae LycoYeast strain. The production of β-ionone was measured by GC-MS. Figure 1 shows the mass spectrum of a CrtY expressing strain.

Figure 1: Production of β-ionone upon galctose activation

β-ionone is produced in vivo by our strain when it is induced by galactose. On the right are presented the mass spectra that correspond between the standard and the observed peak

This promoter TEF1 works under those lab conditions.
