pMIT1-PRM1
PRM1 gene expressed by the PMIT1 promoter.
Usage and Biology
Upon methanol induction, PPRM1 expression of the homogeneous PRM1 gene is activated, and further amplified via the self-upregulation of Prm1. Prm1 then activates PMIT1, upregulating the expression of the homogeneous MIT1 gene and the heterogeneous PRM1 gene. This overall leads to a strong activation of PAOX1 expression of the AOX1 gene.
Unlike in the wildtype P. pastoris GS115 where PRM1 gene expression is then inhibited by Mit1, in the pGMP1-PAOX1-GFP strain, the heterogeneous PRM1 gene is constantly self-upregulated due to the upregulation of PMIT1 by Prm1. This leads to an overall upregulation of the expression of PAOX1 transcription factors and hence shall further up-regulate PAOX1 activity compared to wildtype P. pastoris GS115.
Given that in constructed strains, PAOX1 not only expresses the yEGFP3 reporter gene, but also the homogeneous AOX1 gene, the pGMP1-PAOX1-GFP strain should not only have a higher GFP yield compared to the PAOX1-GFP strain (see part BBa_K3239007) but also exhibit higher growth rates since it should be more capable of metabolizing methanol.
