Introduction

The promoter Teto7 is an inducible promoter with doxcycycline. It must be used with the part coding for the activator protein rtTA advanced (BBa_K3930019). The sequence comes from the publication (Garí et al. 1997)

Results

Production of β-caotene (BBa_K3930003)

The part (BBa_K3930002) was linearized and transformed into the S.cerevisiae LycoYeast strain. The production of β-carotene was measured by HPLC. Figure 1 shows the chromatogram of a induced strain with 10 μg.ml-1 of doxycycline.



Figure 1: Production of β-carotene upon doxycycline activation

β-caroteneis produced in vivo by our strain. On the right are presented the mass spectra that correspond between the standard and the observed peak


This promoter Teto7 isn't negatively regulated and is always active under those lab conditions.
