PGAP

Introduction

Glyceraldehyde-3-phosphate-dehydrogenase (GAP) promoter is one of the strongest constitutive promoter in Pichia pastoris[1].

Characterization

In order to test the function of PGAP, we construct "PGAP-EGFP-terminator" (Figure 1). If PGAP is functional, we can test the fluorescence intensity of EGFP in supernatant samples obtained from the culture of recombinant P.pastoris GS115 strain.

Figure 1 Gene circuit of PGAP-EGFP-terminator

Our results matched the general expected trend (Figure 2). After fermentation experiment in BMMY medium containing 1% methanol. The fluorescence intensity of the samples of recombinant P.pastoris GS115 containing the EGFP gene was essentially unchanged over time. At the same time, we measured the growth curve of the strains.

Figure 2 Fluorescence intensity and OD600 absorbance of samples obtained at different time points from the culture of corresponding recombinant P.pastoris GS115 containing EGFP gene.
