Further information: The plasmid was constructed as follows: 1) The Trypanosoma cruzi trans-sialidase coding sequence (TS) was isolated as a StuI/MscI fragment from pCAGGS-TS and ligated into the SmaI opened pMa58 vector, resulting in the intermediate construct pMa58TSvoll; 2) The start codon of the mature TS gene was extinguished by site-specific mutagenesis using the synthetic linker 5'-CCGGGTGCCAGCACGTGGGGGAATTCCC-3'; 3) Finally, the mature TS gene was isolated as a PmlI (partial)/XbaI fragment and ligated into the SnaBI/AvrII opened pPIC9 vector, leading to pPIC9-TS.
This plasmid is useful in P. pastoris strains for secreted expression of trans-sialidase under control of the strong, highly-inducible P. pastoris alcohol oxidase 1 (AOX1) promoter.
At the fusion junction between the prepro secretion signal sequence (ppMF) of the Saccharomyces cerevisiae α-mating factor 1 gene (MFα1) and the mature 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.
Other name of the plasmid is pPIC9-TSj2.
