pPIC9K-His-DDDDK-Vg

Vglycin gene and DDDDK were inserted to the plasmid pPIC9K ang then transformed into Pichia pastoris. We designed the new plasmid in the experiment to massively produce Vg. The plasmid pPIC9K-His-DDDDK-Vg, which we constructed and used, has an AOX 1 promoter, an α-factor secretion signal, and a plasmid AOX 1 terminator, it is convenient to insert and express the target gene and purify the recombinant.

Usage and Biology

This composite part contains three His-tag (BBa_K5384006), the Vglycin gene (BBa_K5384001), the Enterokinase recognition site (BBa_K5384002), the Asp-pro acid-sensitive site (BBa_K5384003), and the AOX 1 promoter (BBa_K5384004), and α-secretion signal peptide (BBa_K5384005).

Application

After inserting the Vglycin-encoding polypeptide gene into the plasmid, we transformed the plasmid into Pichia pastoris to produce Vg. The plasmid pPIC9K-His-DDDDK-Vg we constructed and used has AOX 1 promoter, α-factor secretion signal, and plasmid AOX 1 terminator, which facilitates insertion and expression of target genes and purification of recombinants.
