摘要 文山松毛虫质型多角体病毒(DpwCPV)S8 片段被克隆和测序,该片段全长 1332bp,编码 390 个氨基酸组成的分子量大约为 43kDa 的蛋白 P44。根据本实验室测定出的马尾松毛虫质型多角体病毒(DpCPV )基因组全序列,设计引物,扩增出文山松毛虫质型多角体病毒 S8 部分片段,并亚克隆出 p44 基因序列,然后将 p44 基因序列 cDNA克隆到表达载体 pET-28a 中,构建成表达质粒 pET-S8,用 IPTG 诱导大肠杆菌 BL21,经 SDS-PAGE 证明 p44 基因在大肠杆菌中获得成功表达,并对其编码蛋白序列进行了分析。 The nucleotide sequence of Dendrolimus punctatus Wenshanensis cypovirus genomic segment 8 (S8) has been determined. S8 consists 1332 nucleotides and encodes a putative protein of 390 amino acids with a molecular mass of approximately 44kDa (P44). Then, the fragment containing p44 gene was inserted into pET-28a expression vector and expressed in E.coli BL21. SDS-PAGE results showed that p44 gene has expressed.
