[Secretory expression of salivary ATP diphosphohydrolase (apyrase) from Aedes albopictus in Pichia pastoris].

The gene-coding mature apyrase protein from Aedes albopictus was amplified by RT-PCR and cloned in frame with the a-factor secretion signal peptide into Pichia pastoris secreting expression vector pGAPZalpha-A resulting in the pGAPZa-A-apyrase. After being linearized by Bln I restriction enzyme, the recombinant pGAPZalpha-A-apyrase was trans-formed into Pichia pastoris GS115 by electroporation. Recombinant strains pGAPZalpha-A-apyrase/GS115 were screened on YPDS plates containing Zeocin and identified by PCR. The recombinant protein of apyrase (M(r) 60000) has been expressed in the supernatant of Pichia pastoris.
