Yarrowia lipolytica TEF1 promoter with an intron

Promoter from the Yarrowia lipolytica Translation Elongation Factor 1 (TEF1) gene with the first intron.

Usage and Biology

This is the natural promoter found in the wild-type Yarrowia lipolytica for the Translation Elongation Factor 1 (TEF1) gene. TEF promoter is among the strongest constitutive promoters found in Yarrowia lipolytica. Inclusion of the first intron of the TEF1 gene in the promoter sequence has shown increase the expression levels (1). It can be placed immediately upstream of a coding sequence for Y. lipolytica.

The wild-type sequence of this promoter contains BsaI, PstI, and SpeI restriction sites in the promoter section before the intron sequence. Therefore, single-nucleotides changes that match the ones in the functional BBa_K2983050 promoter were made to remove these sites.
