Figure 4From: Recombinant protein expression in Pichia pastoris strains with an engineered methanol utilization pathwayTranscription analysis of the co-overexpressed MUT pathway genes DAS1 / FLD1 / TKL1 in HRP/CalB overexpressing strains. The transcript levels were normalized to the corresponding transcript levels of ARG4. The increase in AOX2 transcript levels indicated successful induction with methanol. All co-overexpression strains showed elevated transcript levels of the respective target mRNAs compared to the benchmark strains.Back to article page
