1.
To produce PBD-1with bioactivity in Pichia pastoris,according to published amino acid sequence of porcine β-defensin 1(PBD-1) and the partiality codon of yeast,the PBD-1 gene was synthesized by PCR and cloned into pPIC9K to construct the recombinant expression vector pPIC9K-PBD-1,the obtained recombinant plasmid was linearized by SalⅠ,and then transformed into SMD1168 by electroporation.
PBD-1是猪防御系统起重要作用的抗菌小肽,为实现其在毕赤酵母中的表达,根据已发表的猪β防御素1(PBD-1)氨基酸序列和酵母偏好密码子,用PCR方法获得PBD-1基因,克隆到分泌型表达载体pPIC9K信号序列α因子之后,构建重组表达质粒pPIC9K-PBD-1,用SalⅠ将其线性化后转化毕赤酵母SMD1168,采用PCR法筛选Mut+表型,在AOX1启动子调控下,分子量约4。
