绵羊肺炎支原体P109'蛋白的分子特征及抗原性分析
Molecular characterization and antigenicity of Mycoplasma ovipneumoniae P109'protein
摘要
Abstract
To study the structural characteristics and immunogenicity of P109'protein of Mycoplasma ovipneumoniae,bioinformatic analysis was performed and a truncated fragment ofpl09'was amplified by PCR and cloned into a pET-32a (+) vector so as to construct prokaryotic expression plasmid.The reactionogenicity of the protein was evaluated by Western-blot.The results showed that p109'was homologous with the genes that encoded the hypothetical protein in Mycoplasma dispar,the p102 gene in Mycoplasma hyopneumoniae and the gene that encoded the P102-1ike protein.The recombinant protein was successfully expressed in Escherichia coli BL21 (DE3) as an included body.The purified recombinant protein reacted with the goat serum against M.ovipneumoniae,suggesting that the P109'protein has a good reactionogenicity.The results obtained in this study provided useful information for future investigation of the functions of the M.ovipneumoniae protein P109'.关键词
