pPICZα
pPICZα A is a 3.6 kb vector purchased from Invitrogen. It is used to express and secrete recombinant proteins in Pichia pastoris. We import digesting site of EcoRⅠ and PstⅠinto polyclone sites to make it a standardized carrier.
Recombinant protein are expressed as fusions to an N-terminal peptide encoding the Saccharomyces cerevisiae α-factor secretion signal.The vector allows high-level, methanol inducible expression of the gene of interest in Pichia, and can be used in any Pichia strain including X-33, SMD1168H,and KM71H. pPICZα contains the following elements:
• 5′ fragment containing the AOX1 promoter for tightly regulated, methanolinduced expression of the gene of interest (Ellis et al., 1985; Koutz et al., 1989; Tschopp et al., 1987a)
• α-factor secretion signal for directing secreted expression of the recombinant protein
• Zeocin™ resistance gene for selection in both E. coli and Pichia (Baron et al., 1992; Drocourt et al., 1990)
• C-terminal peptide containing the c-myc epitope and a polyhistidine (6×His) tag for detection and purification of a recombinant fusion protein (if desired) Three reading frames to facilitate in-frame cloning with the C-terminal peptide.
Usage and Biology
The series of products of Pichia pastoris expression systems developed by Invitrogen are mostwidely used ones and contains many advantages as follows:having a strong promoter which can be regulated by alcohol oxidase, being able to fermentate at high density and the recombinant protein having a high expression quantity. The exogenous genes integrated in the yeast's genome can be stable.Meanwhile, after the expression,translaion and modification, the exogenous genes will be secreted to extracellular by the efficient secretory expression plasmid,which can get the avtivity of the exprssion protein improved and be benefit for the purification of the product.
