Figure 2From: Repressible promoters – A novel tool to generate conditional mutants in Pichia pastorisComparison of promoter strength of the repressible promoters under non-repressing conditions compared to P GAP . eGFP fluorescence of the strong and constitutive GAP promoter (P GAP ) is set as 100% and the other promoters, in their non-repressed form, are shown as relative values (in %) compared to P GAP .Back to article page
