Abstract: The gene-coding mature apyrase protein from Aedes albopictus was amplified by RT-PCR and cloned in frame with the α-factor secretion signal peptide into Pichia pastoris secreting expression vector pGAPZα-A resulting in the pGAPZα-A-apyrase. After being linearized by BlnⅠ restriction enzyme, the recombinant pGAPZα-A-apyrase was trans-formed into Pichia pastoris GS115 by electroporation. Recombinant strains pGAPZα-A-apyrase/GS115 were screened on YPDS plates containing Zeocin and identified by PCR. The recombinant protein of apyrase (Mr 60 000) has been expressed in the supernatant of Pichia pastoris.
