pPIC9K-His-DDDDK-Vg

Vglycin gene and DDDDK site were linked to plasmid pPIC9K after inserting Vglycin coding polypeptide gene from Pichia pastoris plasmid. We designed the new plasmid in the experiment, because we need to transform Pichia pastoris to express our target protein Vglycin, the plasmid pPIC9K-His-DDDDK-Vg, which we constructed and used, has a replication origin of the Pichia pastoris plasmid, an AOX1 promoter replication promoter, an α-factor secretion signal replication signal, and a plasmid AOX1 terminator replication terminator, it is convenient to insert and express the target gene and screen out the recombinant. The Ori site of the Pichia pastoris plasmid was derived from the Pichia pastoris plasmid.

Usage and Biology

This composite part contains three His-tag tags (BBa_K5384006), the Vglycin gene (BBa_K5384001), the Enterokinase recognition site (BBa_K5384002), the Asp-pro acid-sensitive site (BBa_K5384003), and upstream the AOX1 promoter (BBa_K5384004), and α-secretion signal peptide (BBa_K5384005).

Application

After inserting the Vglycin-encoding polypeptide gene from the Pichia pastoris plasmid, the Vglycin gene and the DDDDK site were ligated to the plasmid pPIC9K. We designed new plasmids in our experiments because we needed to transform Pichia pastoris to express our target protein Vglycin, and we constructed and used the plasmid PIC9K-3His-DDDK-vg with the replication start of the Pichia pastoris plasmid, AOX1 promoter replication promoter, α-factor secretion signal replication signal, and plasmid AOX1 terminator replication terminator, which facilitates insertion and expression of target genes and screening of recombinants. The Ori site of the Pichia pastoris plasmid was derived from the Pichia pastoris plasmid.
