|Further information:||The plasmid was constructed by exchanging the MluI/NotI (filled in with Klenow DNA polymerase) fragment from pPIC9-TS, containing the C-terminal part of the mature T. cruzi TS gene, by the MluI/ClaI (filled in with Klenow DNA polymerase) fragment from pCAGGS-TSE, containing the C-terminal part of the mature T. cruzi TS gene provided with a C-terminal E-tag.
This plasmid is useful in P. pastoris strains for secreted expression of trans-sialidase ligated to an E-tag under control of the strong, highly-inducible P. pastoris AOX1 promoter.
At the fusion junction between the S. cerevisiae ppMF and the mature T. cruzi TS gene, a (Glu-Ala)-dipeptide and an additional (but not essential) Tyr-residue are present. During secretion of the protein, the (Glu-Ala)-dipeptide is removed by a dipeptidase.
The presence of the P. pastoris HIS4 gene and two P. pastoris AOX1 regions (the AOX1 promoter and the AOX1 3' flanking region) allows integration of the linearized vector into the Pichia genome via homologous recombination at the his4 locus or AOX1 locus respectively.
The plasmid contains a modified P. pastoris HIS4 gene: the internal BamHI site is removed.
The nucleotide sequence of this plasmid corresponds with the EMBL Nucleotide Sequence Database accession number LT727317.1.
The nucleotide sequence of the T. cruzi TS cds corresponds with the EMBL Nucleotide Sequence Database accession number AJ276679.1.
The nucleotide sequence of the pPIC9 vector corresponds with the online Invitrogen sequence.
Other name of the plasmid is pPIC9-TSjE.
