Mutant of TEF1

Mutant of TEF1 Yeast promoter; Constitutive expression

Transcription elongation factor gene promoter of Saccharomyces cerevisiae constitutive expression promoter in the commonly used system. According to the element and registry and database of synthetic biology database bioparts for synthetic biology (http://npbiosys.scbit.org/regulatoryelementdetails/00007) design and synthesis of tef1 mutations.

Contribution

Saccharomyces cerevisiae is a typical eukaryote, so it is very important for us to choose a suitable promoter to express genes.

In our project, we need to express three genes on one plasmid. In the process of consulting the literature, we found an article called "A Cas9 based toolkit to program gene expression in Saccharomyces cerevisiae" [1], which described in detail the relative strength of different promoters in different media and culture time. In the follow-up experiments, we referred to this literature, selected the promoter of appropriate intensity, and achieved good results. So we share this article here, hoping to give a reference to our friends who haven't read this article yet.
