Abstract: Bacteriocin E50-52 gene was designed according to its amino acid sequence and cloning site of constitutive secreted plasmid pGAPZαA,then synthesized,inserted into pMD18-T. Recombinant pGAPZα- Bacteriocin E was constructed by ligating the digested target gene and pGAPZαA with XhoⅠ and XbaⅠ. Recombinant Pichia pastoris was constructed by transforming linearized recombinant plasmid in strain SMD1168. Sequencing result of recombinant vector and genome of Pichia pastoris indicated this expression plasmid was successfully constructed.

Key words: Bacteriocin E50-52; gene design; Pichia pastoris; constitutive expression vector
